bias ply all the way! Radials are just going to make you chase your tail and are a waste of time on a stick car, my buddy had the problem with his mustang...as far as I know the biggest difference between the hoosiers and M/T's is that the hoosier is softer...I run the M/T's myself, in the 28x12.5 size, and they work awesome..I have about 12psi in them hot when i run, and the wrinkle and bite hard!

Also, in regards to driving with radials on the front and bias plies on the back- I have 165/80R15 skinnies on 4" rims up front with my e/t street's in the back...I drive my car everywhere like this! the two hours of highway to the track, in downpours, etc....you name it i drive it....It's really no big deal, as long as you watch for the tar lines lol...to all the guys I know who say its crazy, I say sack up because you don't know how to drive obviously

good luck
