Thank you for the feedback. The overwhelming consensus is that a 7-8' dish is a BAD IDEA for a G-5500, mostly because of wind load. I got some interesting links and pictures of folks with big dishes. Most "rotators" were a variation of the standard dish setup, and a few folks mentioned the Alph Spid as a viable option for such a dish.
I currently have the following on my G-5500: short M2 2M array, short M2 435 array, 8 turn 435 helix, 20 turn 1.2G helix, and a 32" dish. It's a pretty full load :)
Guess I'll store the dish for while and dream....
