Honestly if you want a playful park board I would go with the Evo over the SL. I just picked one up and got to ride it for 2 days and it's a freakin blast. Super forgiving, doesn't catch edges, extremely fast edge to edge, eats up powder, slush, groomed, has tons of pop and is easy to press and butter. Only thing it doesn't do well is take the shit, so if you want to hall ass through chopped up snow this isn't the thing to do with it. It handles all mountain really well for a park board, so if you already have a freeride board I would go more park.
