I just got back from Vegas, and although I didn't light it up, I thought the lanes were fair and very playable. I had a double or turkey going into the 10th frame 4 times (3 times was in the team event, ugh), and split all 4 times, costing me lots of pins (of course).
To me, and the other OC experienced bowlers in our group, the S & D shot was pretty much the same as past years. The team shot is indeed demanding...I used my Track legion Solid all 3 games and was migrating left on the approach as more frames were bowled. So basically, from what I read on here and elsewhere is correct....use a solid with medium surface (the legion is 2000). The main deal is to repeat your good shots, something I failed to do.
