I liked the Coal a lot, very stable at speed and very nice to carve. But not the best dampening. It's a "morning groommer" board. If you don't have to handle rutty runs, it's great. Haven't been in fresh with it so can't comment on that.
How about a Burton Custom X?
Have you tried a hybrid rocker? The Raptor has a pretty different shape than the Coal... One very nice aspect of the Raptor is the good dampening. You'll ride in moguls and afternoon crud as well as in the well prepared runs. Not the case with the Coal.
Husband likes his Raptor and charges as fast as physics allow, has no issue with stability, but admits that the Cusom X was a bit better for charging. I didn't like the sloppy feeling of the rocker while straight lining. It"s not my shape. It is surprisingly good at carving though... It'll also be good in pow, not excelling, but e.g. better than the Custon X. It's a trade off
. All in all a great all mountain board - IF you like rocker between the feet.
Other rather stiff camber hybrids with a very stable ride are the Ride Highlife and the Jones Flagship (my favorite, though it also lacks dampness). Others will hopefully recommend more, but these were the ones I've tried.
