The Hammer rocks. Got one and love it. Good for full rail turns, and switches from rail to rail very smoothly. The fat rail makes it sweet for waves, but not so good on the flat.
And it blasts through the chop better than anything I've ridden. I think its the drawn out tips, which lose a little early planning but don't catch the lumps, and the double concave. But whatever its really smooth in scarborough chop and its great on the waves like Corey said. I find it holds its rail really well too and loads up for great boosts.
When I bougth it I was thinking about a surf board style board for the waves but then thought my toe side is average and I still want to be able to jump so the hammer was the obvious choice.
