Agreeing with Mr. Fodder here, I have a Phenom which I ditched for the Mini, All upgrades for these like Bi Pods ( who ever gets the time to flip it out, mount up and look down sight?) Red Dot sights? unless using FS rounds you'll never hit the target in the sight anyway, range and accuracy aren't good enough on any of them to hit a point first time, sustained fire you won't be looking through it to the target anyway, I took the stock of my Phenom as was too bulky and never actually used it, much better to tuck in close as possible, shrouds etc are just a waste of time unless you want to Join the Spec ops branch of paintballer.
If your doing mag fed go for it, if not stay simple, like jack.
And Mr. Fodder, sadly it doesn't happen at my site, I am looking at changing for the next walk on, fed up with it, Campaign nearby is a good site, and they have 2 marshalls per game so it's all good.
Hope they don't mind my 25BPS.
