This really, really depends on what format you're playing and table conditions. I play the low STTs and I'm CBetting 80% of the time against 1 opponent. Far, far too high, I know, but I'm successful 65% of the time. Helps that I always have a tight table image.
Also, in this format you really can't be raising pre too much then playing weakly once you miss the flop. You'll soon find yourself as the short-stack, or blinded out. Plus these are bounty tournaments, so once you get short your FE is virtually zero and you will get callers, usually multiple callers.
So, for FR cash, I'd say WVH is about right, but be aware that this number should vary depending upom the game type/ table conditions you are playing.
