Best Advice Ever For Straight-In Shots?

Light grip pressure. As light as you can stand.
No side spin at all because you don’t need it anyway.
Connect the balls where they touch the table….
Anytime I’m 98% straight in or similar I address the cueball at the very bottom at the start, it helps me find the center axis and also visually makes the center of both the object ball and cueball more clear(where they contact the cloth).
Also do the same thing on break shots(when not using a cut break of course).

Dead straight in? Pretend the ball isnt there, and aim to scratch
How about: Shoot it just like every other shot. As soon as you start thinking "special", your brain gets in the way of your body.

This is the double-edged sword of practicing straight-in shots specifically (and I believe Dr. Dave's website even touches on it). Once you start practicing them, it's hard to not think of them as "special" shots. Especially if you chose to practice them because you struggle with them. Knowing you've spent time practicing them can increase the pressure you put on yourself to make them.
Actually the opposite: greater cut angle = less throw.
Here's where maximum throw occurs:
- straight (full) shot: 1/2 maximum sidespin = maximum throw
- half ball (30°) cut: no sidespin = maximum throw
For cuts thinner than half ball, you need to add some outside spin to maximize throw - this illustrates that greater cut angle = less throw.

Isn't this a good idea for nearly all shots?
According to Dr. Dave's paper on SIT, the greater the cut angle, the greater the maximum SIT you can achieve.
With slow speed, stun, and 1/2 maximum sidespin, that creates the maximum SIT for a straight in shot, but that isn't the maximum SIT you can achieve for all cut angles.
Maximum SIT for a 1/2 ball hit is higher than for a straight in shot, AND it requires more than 50% of maximum sidespin to achieve--it actually requires over 80% of maximum sidespin.
For thinner cuts than half ball hits, you need 85-100% of maximum side spin to achieve maximum SIT. And maximum SIT will be higher for those thin cuts than the maximum SIT for a straight shot.
Here are the graphs that show everything I've stated:
The maximum SIT (as an angle) is on the vertical axis, and the cut angle is on the horizontal axis. Below is a graph showing the spin required for maximum SIT at each cut angle:

I'm familiar with Dr. Dave's info on SIT - in fact, I'm a contributor to his "resource page" on it (link below). My understanding is that maximum SIT is achieved with a straight-on stun shot (with half maximum sidespin) and it gets less as the cut angle gets greater. Dave taught me that (and lots of other things), so I'm pretty sure he agrees.

I correct my walk up yrs ago, it changed everything for the better.
Yet, you seem incapable of reading a simple graph that belies what you say.
According to Dr. Dave's article on SIT, your understanding is wrong.
You would be surprised: Dr. Dave asked me where on his site it said that maximum SIT occurred with a straight shot, so that he could change that. I replied that his website doesn't quite say that--but it implies that--and other websites actually do say that, because, like you, they misinterpreted what Dr. Dave's site says, so there's this fallacy floating around out there that maximum SIT occurs with a straight shot. Here's what Dr. Dave says at your link:
See the parenthetical phrase at the end that qualifies the whole statement before it? The following sentence has the same meaning:
That does not mean that for a straight shot you can achieve more SIT than with other cut angles, rather it gives you instructions on how to get maximum SIT with a straight shot. Yes, it's poorly written, and when I first read that passage, it raised questions in my mind: "How much SIT can you achieve with other cut angles?" Then I finally stumbled on Dr. Dave's article on SIT that contained the graphs that show how SIT varies with cut angle, and the nagging questions I had about SIT were all answered. Look at the SIT graph: it's pretty clear that all cut angles up to 80 degrees have higher maximum SIT than a straight shot. I'm not sure why you are having such a problem comprehending the graph. This is what it says under the graph:
Do you still want to claim that Dr. Dave believes maximum SIT occurs with a straight shot because you contributed to the SIT resource page?
Somehow you can get Spin Induced Throw with no sidespin on the cue ball? Neat trick. Do you think that Dr. Dave agrees with you that maximum SIT for a half ball hit occurs with no sidespin on the cue ball?

None of you seem to be addressing what I think may be the largest factors in SIT, how clean the balls are and humidity.

We don't seem to be making progress convincing each other. Maybe Dr. Dave will weigh in.

Darrel Appleton’s video works for me, it’s helped several other people I’ve shown it to.
I’d link it if I could, it would probably take me the better part of a day & I’d probably be reprimanded for violating a rule & possibly banned from all pool rooms on earth.
Have a nice day

Maximum SIT is possible with a cut angle, but more spin is required. Max SIT for a straight shot occurs at about 50% max spin. For a 1/2-ball hit (30 degree cut angle), you need about 85% of max spin to get max SIT. The biggest cut angle where your can still get maximum SIT is about 60 degrees. All the details are here:
