A lot of these boards posted here look like strapped towed by kite sort of boards. if that's your style then fine, but reading your first post seems you want something more like a surfboard that rides like a surfboard and the kite drifts.
Me, i think Delta designs are more for down south waves, but could be adaptable. THe 5"11 pictured looks good, but an accelerating rear, interesting. My thoughts are generally with a kite you are going fast and dont want to go faster, more control and slow it down, be able to stomp the thing. That being said i am not pro and still learning about shape design.
Glass, well if you arent jumping like a crazy Will -de-beast (you know who he is) then id go standard poly glassing. then you really feel the board, not like those stiff terrible epoxies. COming from windsurfing yeh they get going better and are faster but feel dead. Just tried a super light blank the pro's use for surfing. feel is unbelievable, but dont recon it would last long for kiting. But if makes you realise the difference. Just gotta make the compromise.
Ill throw "VON" up in the list if you want a board for local and/or bigger waves. Ryan Von Dresselt has been shaping for a long time, learning from some champ shapers and shaping for some big names along with local rippers. Performance short boards are his thing and he is shaping like a champ at the mo, is right in the zen. I have one board from him, currently trying some of his new designs in prep for getting my next shaped.
My current board is sweet, i love it. 5"9 but a bit of width and nice fat tail, feels sweet for 14-20 knots, but too much volume for above that or bigger gruntier waves. Next board will be more for this, less volume, bit more radical.
He has enthusiasm, he has knowledge and he has character. 3 prerequisites for a good shaper.
THat being said i dont think you could go wrong with COlin, Katana or Marty but you asked for details.
I have been in contact with Marty since putting the post up. Basically I'm waiting for him to shape a scaled up board of the one Slack posted pictures of. He mentioned somewhere along the lines of 6 x 18 3/4 x 2 3/8. Sounds exactly like what I'm looking for, but we will see. Demo Demo Demo.
As for the "accelerating rear".... I asked Marty specifically about the tail and he said It will perform like a swallow, He put a bat tail on it as the tail is quite wide and a lot of surface area would be taken out with a swallow.
Pretty excited to get a demo as I don't know a whole lot about board design but know what I like once I have ridden it.
Really enjoyed this thread so far, Thanks everyone for your input.
