Sorry simply not true plenty of amatures have equal knoledge of pro's in all areas of the game ,, the difference is in thier playing ability and thru trial and error they find what works best for them tips shafts strokes what they can make what they can't
I would not give a decided edge to a player of equal talent just because a pro was coaching him , unless it's one pocket , or straight pool or players of little skill to begin with
Execution is where most games are won and lost pro's simply do that on a more consistent basis that's why thier pro's
I actually have found many pro's don't know much outside of what they like thier knoledge is very limited in the science of the game ,
Darren probably is one who's took the time to learn those things

Yeah no.... I have never walked away from a discussion with a player at the pro level regarding tips where I came away without some added insight from a new perspective... It usually comes down to style of
play and their preferred ball speed and shaft choice that establishes the choice in tips and therefore colors their opinion....
Different shafts and different ball speeds are going to have different synergy with different tips/ spring rates.... Same shaft 2 different players and they may have totally different opinions on a tip....
An amateur may have a mental understanding of tips and "pool physics" but that doesn't mean that they have a concept equal to a professionals even if they have the same tip, same shaft and use the same ball speed because they won't have the refined stroke.. It's applied vs hypothetical.. It's like saying a local fiddle player knows the difference in a fiddle vs a Stradivarius as well as a concert violinist at the top of his art.. "Well they both play a tune"...
Darren's comment actually sheds light on his playing style... He tries to manage his game so there are no big strokes needed.. He can come with them when needed and is in the same vein as Alex, Oscar, Ralf and Corey... On the other side you have players like Shane, CJ, Earl and Shaw who seem to try and over power a table....
I'd suggest seeing which player plays your style and finding out what equipment they are actually using... What is advertised is not always the truth and these guys don't eat if they are missing...
I have spent 6 years testing tips and making them... I can tell you that different tips on different shafts will give you different results PLAYING... I can tell you that a stiff shaft with a soft tip will be totally different when you put a super soft on it even in deflection at lower than high speed.... I can give you hardness ratings and COR ratings and spring rates...
Does this mean I would discount Darren about a soft tip on a shaft I have never played that he relies on to be top 10 in the world? Not on my life.. Not today and likely not tomorrow........
