Quick detach/attachment is very helpful. Different stages may have you laying, crouching, crawling, climbing, etc, etc. And you will want to be able to move your stuff around and not have to completely unstack everything off the belt. Also if it's a single gun stage, you can ditch all the extra stuff you won't need for that run. You will most likely buy a bunch of different stuff and have a big old pile of stuff you like for different reasons. Good luck and go watch/shoot some matches and see what people are using
