-Cleaning Out the Barrel
-inserts are weak if you don't have Stainless Steel Ones
I've been using the Freak for a couple months now and I like it. Easy to change out the inserts and its pretty accurate. My only concern with the barrel system is that it is easy to damage the Freak Inserts. It's also a little difficult to clean, but I don't break alot of paint so I could care less. I picked my Freak Kit up for about 90 bucks with a shocker back, and the Ion back came with my Nerve.
If you can find a Freak kit for 80-90 bucks I would say go for it, just be careful if you are using the colored aluminum inserts as they seem to be really weak. I'd recommend using the Stainless Steel inserts because they are alot stronger.
