Same. I shot 3Gun/Multigun fairly seriously for a couple years, but got sick of how much shotgun loading, and how long your tube is, affected the score. But I could have put up with that if it weren't for the TacBros playing loud music from boom boxes or trucks at each stage. One time it was so bad that I had to ask them to turn it off while I was shooting because I couldn't hear the RO. And... got a dirty look for my trouble.
Actually, I could have put up with the shotgun stupidity, and the TacBros. What really turned me off was time plus scoring with any 2 hits on paper. It encouraged bad shooting. Sure, rifle plates and knock-down steel require skill. But squirting bullets at a full size IPSC at 5yds was just too lame for me.
I'd like to try PCSL because of the 2-gun aspect, and hit factor scoring. The targets look good. The rules look good.
