I had a Freak on my Imp, and I did like it. One think i would say would be to get the All American front onto it. It shoots through a lot better than the standard tear drop, plus of course it looks a heck of a lot better.
I'm going with the UL on the fly, mainly because I think it would be rather sick & wrong to put a SP product on a WDP gun. I also found most of the inserts a waste of money and space, i never used anything but the red (.687), blue (.689) and green (.691) plus of course the boomie is what Joy use and It'll match the anno better than the too shiny freak black.
