Thanks for all of the info guys, This should help in my search for a suitable solution. I think my best bet will be to start saving for a 9". Just seems like the logical choice, While i am planning on a relitavely mild 350 for now, I will probably want to increase power at a later time and it only makes sense to do it right the first time so that and make it as bulletproof as possible. if I do that, at least then i can know that i am building on a strong base.
