Dave, your one of the "Good Ones" Bud!! The name of the forum is: Diana Werks Collective. Maybe Harry or one of the others here can post a direct link?? Pretty shure Ive seen Marvin there?? (He is a "Puter Guy"!!LOL!!) About your Diana 350,,,, I remember now,, you got it from Joe Cuz,, (I wanted it LOL!!),, Its been tuned by CDT,, dont get better than that!! If,, however,, you want to pursue "Advanced" tuning to shoot "heavys" in it,, your gonna need to have it "balanced" out internally. Since Bob is retired now,, your choices are limited. I would suggest you,,,,,,,,, stand buy,,,,,,somthins in my garbage------gotta go!! Tim.
