No idea about the Vice, but I was on a D3 RC, until I broke it back in '08, than a RCX, switched to a X7 and love it. To put it simply, maybe a little slower than your RC but grabs more angle easier and is more stable. When I got the X7 I went from running 35 occasionally to running it off the dock almost every set. 6'-3", 180lbs, 67" ski
