You surprise me Jacko.. I'd hardly call a 12' Glide a race board.. IMO it's far from it.
It's my most used board and if I was someone up there and had one I'd be a bit pissed off that I couldn't use it.
Or is your rule so you can stop people using a board like the Starboard Pin?. I think you'd be better to just have a rule that says 'no displacement type boards'.
I'd feel sorry for those who have a two board quiver.. Something like an 8'10" Hokua (or 9'5" Mana) and a 14' Glide.
Also splitting people into pro and amateur is also a tricky one for those who fit somewhere in between.
I'm not complaining..
