What about a 8'6 version of this. this ones 9'6 x 23 x 3 but i've been pondering scaling it down recently (with a wee bit of tinckering in all the right places), think it would make a really fun mid length. Keep the single fin (i ride this one with a 9" larry allison volan flex),no concave, gentle roll in the belly, and very subtle bit of vee through the tail. The widepoint on the template on this is slightly pulled back, rails are really pinched 50/50's, its fast...very responsive, and turns on an absolute sixpence! it has a very relaxed step in the nose, but i'd loose that for the mid length. keep it all about the trim, glide and turns
volume and width can customised, so this can be easy as you want it to be
i've had plenty of people trade boards with me a saunton, and get cracking rides on this first time...its a 'get on and ride' board...no extraordinary skills required, BUT its also fun and exciting to ride...i think the flex fin is essential...but then it was designed with that in mind.
anyways...its just a thought!
You have so many options, and there are so many boards out there. ...enjoy the hunt
