i could but that wasnt really the point, ive been really wanting to give NS a shot after hearing so much hype. sorry if i wasnt clear enough in the original post, maybe i should elaborate a little more on what info i was hoping to get. the 2 main things would be: is the 164 going to work for me weight wise, and are the wider offerings from NS as responsive as they advertise or are they just another wide clunky disappointment. thanks for the response though, i really hope that doesnt end up being my only option. and obviously internet info will only go so far without me actually getting to try them out, i just dont have that option
If you do anything, go for the 164 Cobra. The added stiffness will be needed at your size... and the SL may feel a bit too flexy. The tip/tail shape and hybrid camber will give you enough float to make you happy for sure. For what its worth, the C2 shape in Lib and Gnu boards is so close to NS, they got in to it over patents, so if it's the camber shape you are after, a C2BTX board from Lib/Gnu will make you happy as well.
As for all the hype, yes there is a good amount for good reason, but if you looked at other forums, you would see different boards get hyped, and their reasons are just as legitimate. Don't let some positivity for one brand make you think there is negativity surrounding others.
I'm in the 190-200 lb range, size 10.5 boots, cobra 161. I could get away with a 158, but powder days would suffer. It's plenty responsive edge to edge, holds a carve line very well, will go as fast as you care to let it. Overhang is about as much as I think it needs to be.
At 275, and with size 11.5 feet, your gonna need to stay on a wide.
My opinion is that for what you describe and with your size, you need a 166 cobra x, assuming you want to go never summer.
DON'T GET A WIDE BOARD. You have had how many decks that are wide and you think are sluggish edge to edge? That is NOT because of the board construction it is SOLELY due to width! I bet you would be infinitely happier on all those boards you tried had they been regular width. You really don't need a wide board unless you are over a size 12 boot. I can ride a 25.3 cm waist all day with my size 11s and not have any toe drag. People think you can't have more than half an inch of overhang but you can absolutely handle around 2 inches without toe drag unless you are doing belly dragging carves.
Whatever you do, do not get a wide board. There is no need. If you get a regular width NS, you will probably think it is the best board in the world, but in reality, it will simply be due to the lack of an extra cm of width.
