7' would probably be a good stepping stone for me. I'm 5'11" and about 175 pounds and while I'm not a beginner, taking six years off from surfing after moving to MD from CA didn't do me one bit o' good.
Funny, I was actually looking at the Spherical Revolver on the Harbour website last night to get some inspiration in addition to Gary Hanel's various egg shapes. I haven't bought the blank/kit yet because I won't have a place to work until later this month/early next. Was thinking of going with something from Greenlight. Would be amazing to use the template!
