16oz mercury tube and a $10 "bear tooth" slip on recoil pad using all the supplied inserts really tamed the 12ga Tracker II shooting Lightfields.
I also tried the Lightfield Lites, which shot very nicely with noticibly less recoil, however, I ran out of them before season opened, and couldn't locate any, had to go back to the regula Lightfields in the white box.
