I have both of these ski's and find myself riding the RS-1 more so than the A1.. For me the RS-1 rides a little more in the tail super fast across the wakes and really turns with little effort. On this setup I also use the RS-1 boots I'm a size 9.5 but use the size 10 boots with superfeet and have no problems.. I did see the 2010 stuff last week the new boots are suppose to be true to size, come with the superfeet sole and liners are a bit more slimmed down.. The back rubber of the boot is also not as thick for a little easier release, another cool thing is they are going to offer single mounted plates for the boots so you could run a RTP a little easier.. My A1 has a Reflex hardshell in the front and a Wiley Pro Built in the rear.. This setup is a lot different from my RS-1 and ski's a lot different. The A1 ski's really nuetral for me but does't seem as fast through the wakes they are two very different ski's for me that is for sure, I've switched around bindings from ski to ski and feel that the RS-1's work best with the Radar setup, still trying to get the Reflex system dialed in on the A1.. I'm just starting to get into 32off this year and have a lot more to learn but feel a little more confident on the RS-1 at this point in time.. Hope this is a little help for you but it is really a good idea to try both of these ski's, call Darren @ Wileys he may let you demo both of these ski's??
