Difference between blowers

Does anyone know the differences between the Vortec blowers? There is the A-Trim, S-Trim, SC-Trim, SQ-trim, T-Trim, YS-Trim, etc., etc., etc. What is the difference between all of them and which would be best for a daily driven street car running 8lbs of boost and under?

I'm looking on summit and I see no SQ-Trim. I see a v-1 S-Trim and v-2 S-Trim. What is the difference between v-1 and v-2?

The V1 is the S trim. The V2 is the SQ. They are both labeled as S trims but the V1 is the straight cut (loud) gears and the V2 is the helical cut (quiet) gears. The SC trim is the A trim replacement. They no longer make an A trim.
