Formula Board for a Heavyweight?

[bazza]

6 years ago when I was returning to windsurfing at age 52 and 235 lbs, Roger Jackson advised that I purchase a 2002 Start board with a 70cm fin. I did this and have had fun planing more than I ever have. Recently I bought an 11.0 Sailworks Retro to add to an 8.0.

Although I don't get out on the water as much as I'd like, I want to spend more time sailing in the light air that is prevalent where I live. The Start is a bit heavy so I'm wondering if I would benefit from a formula board or if they don't have enough volume for my weight in light winds where uphauling is necessary. I'll look forward to your advice.
