I havent done it yet. I have a SS freak kit and would LOVE and I mean LOVE to have freaked barrels on my tibs. But at $65 I cant justify it. I think you would still need to use your detents so wouldn't help much with rollouts/ball breakage. Now if you dont have to keep using detents then it becomes alot more worthwhile IMHO. But right now, I cant afford $150 with shipping to get my 2 barrels done.
