^^^^^ This. I shoot 3 gun pretty regularly here in Vegas. At our range we are stuck in mostly pistol bays. For that, IC is perfect. I used LM for a while, but at the average distance we shoot ( less than 20 yes) IC allows me to be a little faster. First find the distance, then determine the choke.

Or, you could shoot LM on everything, and be pretty darn happy. It's versatile.
