Does shaft stiffness affect english?

In pool the "amount" of spin doesn't mean the revolutions per minute (RPMs); it means the revolutions per distance traveled (spin-to-speed ratio).

You can increase RPMs by hitting harder or using a stiffer cue or a harder tip - but that increases the CB's speed too, so the spin-to-speed ratio is unchanged. You can only increase the spin-to-speed ratio by hitting the CB farther from center.

In Europe they refer to the "quality" of the spin. Higher spin/speed ratio is more quality. I think that's a good term.
 
no
go practice your stroke mechanics
you will get more benefit from that

Conventional wisdom here in England is that shaft whippiness affects CB deflection when using English. (Low deflection is generally considered to make it easier to use English and still pocket the OB.)

Does America agree?

Not really. Here's what Dr. Dave says about it.

...typical pool cue shafts are very flexible in the lateral direction (i.e., they don’t require much force to flex), and the shaft does not flex very much during the incredibly brief tip contact time anyway, so stiffness does not have a significant direct effect on squirt.

Fair enough. It seems like the more you learn, the more 'conventional wisdom' has to be abandoned. Thank you.

I'll go through Dr Dave's link later on. I've read the Illustrated Encyclopaedia, but if it was in there I don't remember it.

My earlier reply was only about whether shaft stiffness reduces CB deflection. I didn't reply to your question about whether low CB deflection makes pocketing easier - the answer to that is yes, it does.

I was curious about the effect of shaft taper on cb deflection, particularly the sharp tapered shafts that are used by carom players. I used Ray Schuler's 'constant' tapered shaft for the better part of a year to shoot pool, and I found that I had to make more adjustments for cb deflection than with a straighter taper and larger tip size. Dave's answer to that seems to be a bit ambiguous: The last 5 inches matters and it could be a combination of squirt and swerve.

My shaft is very stiff (conical taper from tip to joint), yet produces the least CB deflection of any shaft I've ever used or heard of - because of its 10mm hollow tip. Not sure how to make that comparison with a "normal" conical-taper shaft.
