Not much difference. I went from Camber to Never Summer's R/C with almost no adjustment. I noticed a difference but it wasn't huge. A little squirrely flat basing on hard pack but that's about it.
The camber sections on the hybrid retain a lot of the feel of camber IMO.
Now, after riding Arbor's rocker for almost a season, and then going back to NS' R/C, that required an adjustment! I got lazy and sloppy with technique on the the Arbors. Took a Cobra out and was instantly reminded that I needed to stay more technical on it. Might just be the cobra though and not r/c in general.
