I have a new log in the works. Right now it's a 9'8Y triple stringer blank. I have some ideas in mind, but to keep things objective...

What features and design aspects really make a longboard excel in the knee-head high range?

I like nose riding, I like making turns. I like catching waves and I'm about 6' 190ish lbs. My current log is a 9'6 stewart performance model. I love it in steep waves and in turns but I'm usually on a shortboard when the waves are actually good. It's fine in small crappy surf, but I can't get all the way up to the nose on it.

Thoughts from experienced longboarders and shapers would be appreciated. Thanks.
