I got P101 installed in my Nautique today. Didn't ski but I did drive one 55kph set. Seemed the same to me. The little bit slow 1,2,3,4,and 5 ball was definitely the same. I didn't tell the skier about the update and he didn't make any comments about different feel. With rev O I never felt anything funny coming off one ball and I never saw evidence of it if the virtual times are to be trusted. Zero Off if you're listening, your customer relations totally suck. Why the secrecy? All I heard during the MAsters webcast was how great Zero Off is. If you really gave a damn, you'd keep your customers in the loop.
