Surf Ski For Somebody 6'4"?

I've been through two of these things so far:

- A TwoGood Offshore that I modified myself by removing the foot wells and
grafting in another - larger - foot well module. Took me about two days
and must've added 10 pounds. Never again.

- A Findeisen about 19' long and 18" wide that fits lengthwise, but whose
seat pan is about an inch too narrow - and which I suspect the maker
took something of a financial bath producing.

I'd like to replace the Findeisen with something that has another inch in the
seat width and maybe another inch in hull width - or at least a little more
stability.

Did the dance with one promising maker and then, at the end, it turned out that
he couldn't give me 48" seat-back-to-heels/50:" seat-back-to-rudder-pedals.

Probably should've gone to Sweden and gotten my legs shortened back when they
were doing that sort of thing.

Something like a poly Wave Witch would probably fit - but I want something that
glides/surfs non-breaking swells.

Anybody have experience in this situation?
