First, Doc are you marketing your SS line for the vertical mount reg? Also there are two holes in the reg on the side marked INLET do both need to be used and if yes what kind of fitting would I use? Second, not to open a can of worms but I'd like to upgrade the barrel soon and would like some input. I like the looks of the AA, our local store has the Dye Boomstick and SP Big Daddy for the Imp and I have a J&J Cermamic and a Lapco Bigshot for my Spyder which both do well(I perfer the Lapco). Should I just wait for Lapco to get a barrel out or would one of the others be better for the Imp? I'm shooting Blaze mostly sometimes PMI Prems. Both work well with the Bigshot.
