Thinking About Pulling The Trigger On A New Board

After playing around on a foamie, an 8' hard board hybrid, and some assorted shortboards, I've learned a few things about my surfboard requirements. My number one priority is that I want a board that moves through the water fast. I returned to my 8 foot Wavestorm (Volume 86L) the other day and paddling was a breeze. I realized immediately that ease of paddling is my first priority- shoulder injuries and mediocre arm strength have made it apparent that I need speed. Based on my need for speed, I've decided I want a longboard because they are faster paddlers and I can get into waves earlier.
The next requirement is an epoxy board. They're lighter, tougher, more buoyant, and I suspect faster (depending on board shape). Duck diving is irrelevant to me, from my experience, because I find paddle speed more important for getting outside than the ability to duck dive. Here's another factor. The longest board I can fit into my car is 8'6" (2.59 m) and that size allows me to not have to hassle with my soft racks. The question I have about the 8'6" board length, I'm 5'11" (1.8 m) 185lbs (84 kg), is whether I can still catch waves further out in longboard territory with that length or whether I will need to stay in the shortboard pack. I'm willing to go longer in board size and hassle with my soft racks if it allows me to get into waves a lot sooner. I'm just not sure what length would be best (opinions wanted). Also, I'm not that interested in noseriding or cross stepping so I want a performance longboard I can practice top-to-bottom surfing with.
I'm considering the Firewire performance longboards (TJ Pro & Flexflight), but I'm hoping to get some other ideas or insight.
