What size surfboard should a 6 foot 250 lb guy buy?

Question

I've been surfing on and off for a few years, mostly long boarding with a Bruce Jones 9 foot something longboard, and I now mostly bodyboard, but I'm looking for a new board to transition to a shortboard. I've asked my local South Bay California surf shops about sizes and stuff and most told me that a 7' - 8' hybrid board would be cool for me. I just wanted to see what kind of input I could get on here before I have one shaped.
