Didn't read through the other posts, but figured I'd chime in since I've owned all 3: Team Gullwing, SL, and Heritage. The Heritage is stiffer than the other 2, and probably more than you need. For the other two they're both very good boards. The SL 158 has more effectgive edge than the TGW 159, and the latter is a click softer. I ended up keeping my SL and selling the TGW at the time because they were so similar, there was no point in keeping both. Pretty much get the one you can find a better deal on.
