I agree on this one. I have almost the exact same set up as this OP. Ion XE with a freak barrel. I, in general, do not carry the whole kit; just the .681, .685, .689, and .693. Most of the time, you won't even need that many. The nice thing about buying the kit though, is that you get the case. I use it to carry a lot more than just the inserts. You can take out some inserts, put in your barrel, o-rings, and wrench.
In terms of purchasing a Freak Barrel, the BST section here is great. Lots of the time you can get an impulse threaded barrel with 2/3 of the most common inserts for really cheap. Just watch out for people trying to rip you off, I can't say I know what the normal price is. I haven't looked at a Freak kit in a long time.
Over all, I must say the freak kit is great. Its easy to use, and has inserts in every conceivable size. It also looks sweet with the All American Front on it. Although I think that that is all fronts do; there is the tear-drop and AA, and I don't think there is a shred of performance difference.
Also, if you have any issues with your Ion XE, call GoG. They are the new SP.
Cheers, and enjoy your Ion. No matter what the haters say, it is a great starting gun.
