I am right in the middle also. I have a DW fibur barrel I use for awhile then I will go back to my CCM barrel kit for awhile. Both seem to work really well, just personal preference. Cant really tell much of a difference as far as accuracy, both will drive tacks with good paint. And honestly don't think you can go wrong with either one.
But I am looking at picking up a Lurker Eigenbarrel .678 barrel. Not the prettiest barrels but they are pretty cheap and just like the idea of a really tight bore barrel.
