I've been riding my Nitro Shogun 161 for about 8 years, so I can handle a long(er), stiff hard charging board pretty damn well. Many of you seem to be recommending getting a 157-159. What are the advantages to that?
I used to ride longer stiffer boards as well, recently switched to shorter boards - they are just so much more fun in the trees, more agile, more playful and versatile. You seem to love trees and moguls/banks. I find shorter boards more fun in tight chutes and steeps, they will still handle well especially the boards I listed before. Also be great in powder with their rockered tips, but very stable with camber under-foot.
Longer stiffer boards are such one trick ponies - they can get boring.
You have your Nitro 161 if you want to blast groomers so i'd start a quiver and pick up a shorter board.
