My main ride is a 151 Graft. I take it all over. While I often ride it outside of the park, it does have its limitations. It won't go as fast a longer, stiffer all-mountain ride. When they snow gets hard, it will give you a VERY rough ride, as it can't cut through crud. At high speeds it gets twitchy. I hardly every get to ride real powder, but I know it would be sketch under those circumstances, too.
All this said, the Graft is still a really fun ride for an "all-mountain" deck if you willing to deal with its inherent limitations. Outside of the park, I have been riding switch about 40% of the time this season. A true twin makes that a great deal easier, and fun. That the deck is small, light, and agile is what makes it such a joy to ride, as you can just throw-it around all over the mountain. I have a tendency to ride trails like I am street skating, so a park board is pretty good for that. However there are still times when I wish I had stiffer, longer all-mountain board based on the conditions and my desire to go fast as I possibly can. Life is all a matter of trade offs and compromises, you just have to figure out which ones you want to make.
