Cannon, do you actually own one?
Seriously, read my springer story. If I got a guy with that, you can definately get a few with this.
It'll hold itself at the same as a normal TM MP5 (maybe a bit lower...) and even MP5Ks are used in some outdoor games, it will definately give you good mobility.
It's all about your play style.
Though, if you're a fat guy that can't run faster more than a normal guy walks, get a upgraded M14 instead.
