WOW, speed glue ban sounds the worst rule, so what is the speed glue?
I also don't like that plastic ball, but who knows, maybe in the future we will get used to it, i can't remember what ball i was playing since 1997 until 2004, if it was that 40mm then what is worse about this ball from 38mm or the previous ball? if so then give this plastic balls a time 4-6 years from now let's say then we can judge, i play with cell and poly time to time and i swear i can't tell the difference most of the time until i look at the ball.
I also agree about 21 -> 11 set, but i played 2 last friday somewhere and they still play with 21 set-points games, i felt either they don't know or don't like that 11 set point rule, or they did this to give more chance for other players to play, as one 21 set points game is almost equal 2 games of 11 set points, but i prefer this 11 so if i lose in first set i may return in next 2 sets, but when i played with them at 21 set points i was able to defeat them all, it was like if i lead to 12-6 or 14-9 they just give up to fight back.
