Wood over CF shaft options

[Black-Balled]

I agree.
Remember the days where guys would count the number of wood grains that ran off the edge of the shaft? Or how many rings there were looking at the end of the shaft? I'm guessing a CF tube eliminates the need for that sort of thing, if there ever really was a need for it.
Also likely reduces the risk of warpage, and since smaller pieces are used in the construction, it should reduce drying times and they can use lower density wood, especially in the core and still have a stiff hit and likely almost all shafts would have the same "hit". And with their lifetime warrantee it probably reduces cost and increases customer satisfaction in general.

A fine summary!

In any event, it is not the way to reduce deflection.

McDermott's Defy carbon-fiber-only shaft also mimics McDermott's effort to make their i-series and G-core shafts non-Revo like. Defy's carbon fiber is different from other companies's CF. As McDermott states on its website about a component in the carbon fiber rod:

SmacWrap, originally designed for the aerospace industry, absorbs vibration and dampens noise resulting in a confident hit with a soft feel and quiet sound.​

OK, it is remarkable stuff, but that accomplishment of a 'confident hit' (read not a Revo hit) and quiet sound (read not a Revo tink) comes at a cost of lessening the energy transfer efficiency to the cue --- significantly. Its a sort of joke but it is an accurate test of relative energy transfer efficiency by dropping a shaft on a pool table and seeing how far it bounces. The higher the bounce, the more energy transferred. Defy doesn't bounce while other shafts do. Proof enough this CF shaft lives up to company hype that their shaft is different. But it comes with a cost of less oomph to each hit.

I just want a little more feel. I understand all the performance aspects of CF. That's why I use CF right now. But CF can't give you feel.

The LD shafts that were made of wood had ' feedback ' problems according to purists.

Many Old School One Pocket players avoided them.

Brand to brand the CF shafts hit different.

I play with a Mezz CF shaft and have no feedback issues.........

Then there is the issue of ferrules, different ferrules play differently............

You are assuming it's everyone goal to make some sort of magical zero deflection shaft. There are many players who are doing just fine with a 30 year old cue with an over 4 ounce shaft that has had no consideration for deflection. Most of those people don't want a drastic change in how they aim if they decide to buy a new cue. A large majority of pool players who are buying these things never even hit a ball with them before the purchase. They just like the way it looks.

Oscar just had a really good run at US Open. He plays with the 12.9mm LP Infuzed shaft because it is not as low of deflection as their other products.

Also, I completely disagree with your assessment of the bounce and energy transfer. Ever hit something with a dead blow hammer?
Just because there is a dampening system within something doesn't change the potential for energy transfer. And some people like a soft, quiet hit.
