Thomo,
The PSH 11 with the right fin set will rip with 87kgs on it! I have seen 3 of my friends ride it that way! I would suggest FG or PC5 inside foil fins and use a center fin adaptor to convert the fin box for the FCS fin! I have my 10'6 set up the same way and Revvin will tell you it kicks a$$!
With this fin set even a beginer can rip turns! The bigger the waves get the better this board performs. The key is to get the Kick Pad right over the middle of the center fin box so your weight is positioned correctly. Get your foot right back on the kick pad during turns and your away! You will think your going to fall of the back initially but the boards primary stability is great!
I have ridden the 11 in 2 x OH and loved it, but it wasnt a threatening wave just a lovely point break!
IMO it is more stable than the gun due to width and also has great glide!
If Jacko has a demo board try it you will be impressed.
The 11.4 naish is also very good board IMO (only surfed it twice at PRK) but handles very differently to the PSH11. The 11'6 naish is far more boaty and if you surf a shoter board, I dont think you will like it for obvious reasons!
The Starboard Wopper, I hear has big board feel and stability and reasonable glide as well due to width and overall volume but I have not surfed one!
It will come down to personal preference and they way you like to surf!
