Thanks for the honest input that's what I was looking for. I was afraid the Gnu might be too stiff for what I'm looking at in a board, but the waist width was attractive. I'd love to do the type of riding its truly meant for, but I'm just not there yet.
They did just update the SL for the 12-13 lineup... hmm, haha. Decisions Decisions. So then it would be roughly down to Cobra (I rarely ride switch unless I'm getting myself out of a jam, and a little more sometimes in the trees), the TRS, the Goliath or the updated SL.
Controlling my weight won't be a problem. I'm the opposite of most people, I work on call and outside so in the summer when I'm not working I'm lethargic as balls. It gets a wee bit hot down here. In the fall/winter months I'm much more active and drop 10 lbs like nothing, with effort 15-20 won't be a problem, I used to cut weight all the time.
So I'm guessing with those, the Cobra is probably the stiffest, and the other 3 are pretty close and more of a which graphic do I like better type of thing. The one thing I didn't like about my SL was that it seemed like it could be a bit soft for when I wanted to absolutely haul ass. Then again I was around 190 when I rode it last season. So if I could drop to 180-185 that might not be such an issue at that length.
NS rates the Cobra and the SL the same for flex, but I believe the general consensus is that the Cobra rides a little stiffer. So that might work. Also if you are still working on your powder riding the Cobra will be a bit easier on that front - and the limitations on switch riding don't seem to be an issue for you.
I has been a while since I have been on the Goliath but I don't think it was much/any softer than the Cobra. If anything, I think it charges a bit better - but is not as easy in deep pow...
TRS is a really good all-around board and the flex is Goldilocks for most people - not too much, not too little, just right (and again not much difference to the Cobra - and it gets stiffer as you go up the size range). Compared to the Cobra it is not quite as good in pow (but still better than the cambered Bataleon) but slightly more free-stylish on groomers as a true twin.
- For pow: Cobra
- For speed/charging: Goliath
- For playfulness: TRS
But they are all really good boards and you cannot go wrong with any of them.
EDIT: Sorry for the comment about your weight. It as not meant as a dig/burn - rather I was getting at the fact that the bigger boards (for heavier riders) tend to be wider, so getting the weight down will help you find something narrower.
