Front tire size????

So, whats the consensus on mixing tires front/rear- meaning: Do you guys run a different brand or model tire in the front than you do in the rear. If I end up going with T/As, Cooper Cobras, or MT drag radials in the back, what would be a good matched tire for a 205/65/15 in the front since none of those tires come in that size???

BrianT- what type of Michelen are you running up front??
