Well I'm SHOCKED no one has mentioned Never Summer yet...but I would throw the Heritage into/onto your list. I was a Lib Tech guy going back to my 93/94 Matt Cummins but because of all the talk on here I tried the Heritage last year and I'm a convert. IMO the only area in which the Mervin boards are better than the Heritage is ice hold. Mangetraction is AWESOME on ice...but I find the Heritage to be more playful than the T.Rice I was riding before it...to me more of an all mountain/freestyle board.
I have a Heritage and for the needs the op stated I think it would be too much board. A SL would be the NS all mountain board that would still be playful enough.
