I'm a beginner to long range tactical shooting, I plan to buy top notch glass to start with, cry once so to speak...I have been looking at the S+B 3-20 due out some time soon. Do you feel the Klein would be a great reticles to use? It seems basic yet advanced enough to be perfect for tactical competitions. The MSR is too busy to me, the H2CMR looks like the Klein but less symmetric, and the P4F doesn't look as good as the Klein. Anyone have opinions they can share?
