Different divisions I shoot in the popularity order I like the:
Lim - I like going fast and dont want to worry about mag changes as much
SS - its fun to shoot my 1911 and i like the challenge of low round count mags and multiple reloads
Lim10 - same as SS except my 2011 instead. That and no one shoots this div so its easier to win
Prod - for S&G at a classifier match mostly
Limited - b/c I showed up to my first match with a magwell and extended base pads on my G34 not knowing anything about classification rules/regs. Have just followed the, "run what ya brung" motto, since.
I used to see T-shirts that said "Your favorite band sucks." Maybe I should get one made that says "Your favorite division sucks." Haha.
Started production because I had already been shooting IDPA for a while, so I just needed to add a couple mag pouches to the gear.
Went to open, because... well... OPEN !!! Huge fun.
Went back to prod when I made the conscious decision to shoot less. I couldn't justify the cost of open (mainly my gun would have only had a couple years left in it then I'd be needing to invest in a new one) given I was only going to be shooting a couple LIIs and a handful of club matches per year.
Prod is fun for it's own reasons, but not AS fun as open. I may give Lim a try in the next couple years since I just need to pick up a glock and a .40 reloading setup.... (although I keep reading how stupid Lim is... haha)
I shot the last two years at Angola shooting L-10 minor from aiwb concealed, because I like the stage planning of a 10 rd game but want to be able to run the gun from aiwb. Now that we are closed at Angola, I'll eventually get out to Fort Wayne or Northwest Ohio and either do the same or limited.
