Okay, first off I think a 157 is a bit long for you if you are planning on doing freestyle (park/pipe). I'm 6'1", 230lbs and I used to ride a 157 as my freestyle board. 153-155 is probably a better length. Remember, the longer the board is, the more you work there is in spinning. Of course, longer boards are more stable at higher speeds. So you have to figure out where to compromise.
That said, I am a HUGE fan of
Never Summer boards. I bought a Premier T5 (freeride board) 165cm last year and love it. But then I prefer all mountain and going fast over going in the park. I would suggest looking into their freestyle board, the Evo which they have at 155cm. The thing about Never Summer is they don't do much with graphics because those don't matter. What matters is how the board performs. And Never Summer boards perform like magic. Not to mention they last and last and last. They don't lose their flex even after years of hard riding. I know a guy who rents the Premiers from his shop and is still able to sell the board at a good price the next season. Just to let you know, the Premiers cost about $450-$500. Not your crappo-cheapo board they rent you at the slopes.
Well hope that helps a bit. Just remember, the graphics should really be the last thing on your mind. You want a board that performs great rather than just looks great.
