Still people are just making up excuses as to why they need one. They have no performance enhancement. What rally got me was a few week ago a handicappied person playing pool with a glove. They man couldn't do a bridge with his hand and was shooting with a mechanical bridge, but sure did have a glove on. If gloves are so good they why are they advertising them like you're not wearing one.
I don’t think that gloves are that great, they are needed in conditions where the cue can get sticky, like humid conditions.
Gloves got more use 20 years ago when all the cheap fiberglass and graphite coated cues came out, like CutTec.
CF shafts also tend to become more sticky and get there faster than wood, this is why players use them.
When I play with a wooden shaft, I don’t use gloves, unless it gets sticky and the house doesn’t allow talc. When I use CF, I use gloves.
Gloves don’t improve performance, they reduce feel and that’s why players are looking for gloves that transform the feel as much as possible. They enhance playability if the conditions are sticky without them.
