I started slalom skiing last year and chose the Synchro with the factory issue Targa bindings. It was great for a beginner. Last week I bought a Strada front boot (use rtp) and Senate C. The Strada boots came in several days before the Senate C so I put them on the Synchro. It really brought the ski alive, I was pleasantly surprised. Today I skied the Senate C for the first time. I was a little anxious because all I've ever skied was the massive Synchro, the Senate C appears half its size and feels half as light. To my surprise I popped right up on it and got comfortable quick (with the exception of the massive amounts of water I took in through my nose on the start. The big Synchro didn't do that). I didn't fall once (probably wasn't skiing hard enough). I didn't get in the course, just free skied at 30 mph but I have no doubt it is much more course capable.  Everything about the ski felt better to me. It felt like going from a SUV to a Corvette. The only advantage that the Synchro has is stability, but the Senate C is plenty stable.  Knowing what I know now, I was late switching to the more performance oriented Strada boot and the Senate C.   If you are comfortable on a ski of any kind, I say go with the Senate C without a doubt, don't be scared of it. As a beginner I've been skiing with the philosophy of making six turns at the balls and eventially they will come. With the Synchro I was only up to 3 balls at 30mph. I have no doubt that all six will soon come with the Senate C and Strada boot. FWIW, I am 37 years old , 5'8" 195 lbs and the 67" Senate C felt fine to me at 30 mph.  Why did I start this so late in life?
