No! Don't cut out the nose kick. Well not too much of it anyway.
I've found that my 7ft Coreban Hyper nose kick has saved me from tiny wave breaches. Plus purposeful nose dives when either thinking I was near breaching or running down sloppy wave swells or chop. The board just bounces back up for me to continue on.
Obviously the higher the wave & fast speed breach is going to nose dive & throw you.
I put this track box in this board when most people were making surf foil boards at much longer lengths a few years ago. I took the gamble & it paid off for me and still using it to this day & love it. It is a bit of a heavy barge to throw around but to carve & glide it's good. The nose kick soon stops pushing water as the board speeds up or when you pump & foil takes over.
I haven't used it yet for winging but will soon try it out.
I think your board at 26 Wide should be fine for winging. More stable than using it to just stand on whilst waiting for a wave if surf foiling. As I found out with my other JP 6ft 8" X 27 wide 95 litre foil board.
