I had looked them up last night after you mentioned them, at first I got mistaken for the cheap Devils in green but finally I found the ones you ment, got some reviews on them too, some people thought they were the bees knees, others thought they were some of the worst they had used! Double feeding being the main problem on some aegs.
Yea the TM perfect hit brand are made using the ball bearing process, they are the ones I was thinking of getting. Like most bbs though they still have some bad reviews.
