Funny you mention that, Nathalie, because I am working on learning the 10 combo premix in PRS#2. Some of the combos are from PRS#1, and I find them tough but doable, with time, persistence, and practice. I really love some of the moves (reverse rockhorse, for one, and the over the top w/the ball change). Some moves I probably will continue to modify to eliminate so many spins, since I have post-50 year old inner ears and get dizzier faster than I did back in my glory days. I am not so worried now that PRS#1 is beyond my graceless self.
