i am trying to decide on a scope. i have looked at the votex viper pst and the sightron SIII in the long range models. i like that in the sightron i can get higher power. the pst tops out at 24 power. does anyone have an experience with both of these or have experience on either one? i am thinking the 32 power for sightron or the 24 power for the vortex.

another question is in english dummy term what is the difference between front focal plane and secondary focal plane?
