M/T ET street radial pro VS.

Any opinions on the mickey thompson ET street radial vs. the ET street radial pro? The size is right at what I use which is the ET street radial 275/60-15 28". I m due for replacement and Im considering the ET radial pro or a small step up to the ET street radial in 295/50-15 which adds approx 1.5" tread on the same size rim, 8".
