I skied two sets yesterday morning, one on my 05TT and one on the 2011TT. ZO was on C1, 05 is still PP. If the boats were identical colors, I doubt I could tell the difference at 28, 32, 35.... I'm in the same boat as Razorskier1 except my wife has absolutely no interest in a newer boat! My 197 skis great and I wouldn't hestitate to buy the 2011 promo running in my neck of the woods.
