Mcdermott Defy Shaft

I agree the balls travel farther. As I said before, rolling on a surface and spinning in place are two different things.

Bringing cushions into to mix won't help clear the waters...

As I asked before, the ball is 3 to 3.5mm larger. Little bit heavier. How much of an effect on spinning a ball in place will that have? 1%? 50% 10 seconds more? 50 more RPMs?

If the ball is heavier, won't it take more stroke power to get it to spin? How much more? Assuming you are already stroking both balls at 100% because you are trying to set a record, does that offset the increase spin you expect to gain from the ball being larger and heavier?

And if we want to bring this conversation full circle, the carbon shaft generates more spin than wood how?
210 grams to 170 grams (approx). is pretty significant. Wouldn’t that weight assist maintaining momentum?
 
I just remembered I was going to try with a couple of different cues. Obviously not scientific, but I feel in the short time I had I played some very similar shots. These were also the first shots I’d played in a few days, so not ideal 😂 (You can see the washing I quickly threw off the table).

Depending how the weight is distributed (we know a ball is even), yes it will.

Is it significant? 40 grams? If the one ball was made of lead and the same size as the cue, how much longer would it spin?

See my point is, maybe that 40 grams makes it spin for an extra 30 seconds, maybe it's 3 seconds.

This goes back to the direction this thread took "the CF shaft causes more spin" How? "Because energy transfer"...

I ask how much better and what if any meaning impact will that have on the end result? And no one can give an answer.

Well we can’t give you an answer that will fit your framing (data driven) because we don’t have a little pool robot to play exactly the same short repeatedly. But a few are suggesting we feel it makes a difference. You’re telling us it doesn’t, but then suggesting if it does, we should be able to say by how much, which is a question you wouldn’t be asking if you were firm in your belief that it doesn’t make a difference.

EDIT: Sorry, that’s not fair. You could be asking that while firm in the belief that it doesn’t make a difference with the target of invalidating our “feeling” that it does make a difference. Clearly we can’t quantify it with reliable data.

You did the experiment and made a video, very nice! Total props to you sir!

I would ask if there is a weight difference between the two cues?

I feel like they’re pretty similar, but I’ll weigh them tomorrow, and I do want to try it a little more once I’ve got my arm going. I feel like I hit a few of them well, but not perfect.

What about tip size? The Player’s cue has a wider tip than the ignite. Would that allow the ignite to hit lower?

The only thing I think I can do to make it as fair as possible is wear a glove, in case friction on my bridge hand is making a difference 😂 Getting a bit nutty, but short of building a little buddy bot to shoot balls for me, that’s all I can do.

When comparing carom ball spin to pool ball spin, yes I'm asking how much of a difference it would make and what does that difference mean? (Is it significant?, Noticable? Any real world impact?)

When it comes to shafts, yes I think it's mostly in your head, if there is a difference, it's small, won't effect outcome of the game, pretty meaningless. For shafts, go with what you like. I play with Fargo 650 that breaks with there playing cue and haven't changed the tip in 30 years.

I like a CF shaft because it's smooth. I got a dent in my wood shaft and I could feel it with my closed bridge. Drove me nuts. It physically had zero impact on the physics of the game, but in my head, it was all that mattered and it was distracting me.

I wear a glove with my Revo 11.8. I never used a glove before, then I tried it and liked it. Now I can't play without one. How much friction does the glove reduce on the Revo vs no glove? I don't have an actual number, but I know it's insignificant and meaningless.

The Defy is a great shaft, I shot with it a shots but I had already purchased my Revo.

Here is something really interesting about the Defy.

Hahahah, I don’t know why I was shocked when the Defy didn’t bounce 😂 It looks really weird just planting itself on the table!
 
But the magnet stuck to it as well?... What the hell is going on inside there? Lol

LOL! He’s awesome.

As a bit of a laugh at cue reviews on Youtube, and in honor of your stance on shafts and tips, I made a Players cue review for you:

EDIT: Apologies to The Billiards Corner for taking the piss a little bit. If you happen to see this, it’s just a laugh ;)

Lol this was awesome! Well done!

What type of table do you have? Looks very nice.

Hahaha, I feel a little bad for taking the piss out of The Billiard Corner’s reviews, but I doubt he’ll ever see it, and honestly, reviewing cues on video is one of the more pointless things I’ve seen done. I get it though. I probably wouldn’t say no if a company offered to send me cues to try out.

It’s a Min table, and the cloth is Takini, also made by Min. They are a Korean company, which is where I live (Jeju Island).

I have to say though, you’ve moved me more towards your position. That’s the most I’ve ever used that cue, and the total filming time for that video before editing was about 13 minutes. The only shot I had to play more than once was the just off straight shot with object ball in the middle of the table, bunch of left hand side to kick the cue ball behind the 9 ball for position on the other side. I’m not going to switch to that cue, but I was a little surprised at the results I was getting 😂

I knew something looked different about that table but I couldn't figure out what it was. Of course it's from the other side of the world!

You look to have a good stroke, you definitely study the game, and test it!

I just started playing 4 years ago. I have a background in electrical engineering. So to accelerate my learning I use physics and math (Dr. Dave style school of thought).

I'm very interested in the physics of what happens and why. I feel if I can understand that, then I know what's possible/not possible when I'm at the table and have to get creative on the spot.

I agree that a little "understanding" can go a long way (even if one doesn't know the "math" and "physics" behind it, which isn't necessary). For more info, see:
