BFG's or MT's Radials?

I ordered a pair of 15 x 8 wheels so I can get bigger stickier tires out back.
With 245x60x14 BFG's my 60's are usually 2.0 or worse. I can squeeze 275x50x15's in there. I am keeping my 14 inch wheels and tires for cruising. I have SS springs and a pair of kicker shocks mounted parallel to the ground that should help it hook. Summit lists four makes in that size: MT's, BFG, Hoosier and Nittos, any suggestions? I'm hoping for more consistent launches.
I have run mid 13's at 104, but I am losing a lot of time getting started.
