8 3/4 rear

thanks for all the info so I take it I could use the 8 1/4 rear is the 8 3/4 that much better or is it easier to change gears because of the design
It's not that much stronger. I have a local friend who used an 8 1/4 in a Demon that ran 11s hangin the front tires in the air every pass and it never broke. I think he still has that rear end.
