This thread seems to be in part intended as a dig at me, but I don't mind.
I started playing with a glove in the early 90's and got stirred a lot. Since then, I lot of my former pool associates tried it out and became converts.
When you've played a lot tournies in humid un-airconditioned bars or other unsuitable venues, then a smooth sliding bridge is a clear advantage for anyone who has compared the two.
Anyway, a glove is hardly convenient, and not typically fashionable but it allows consistancy of feel for speed control, and if you're after consistancy in your game, it provides that advantage.
