I currently have an Aimrite Venom Comp 130 and am thinking about buying a second gun. I think it's going to be a Rob Allen 90 or 100 that I'm going to use to start doing some hunting up my way (NY tri-state area) for striper, tog, etc., and also as a back-up and hole/reef gun when I travel to warmer places. I found an older thread on dual 16s versus a single 20mm band, and it seemed that most preferred the dual band setup so that you can power down for hole shots. Having said that, I do like the idea of a single band. Is a single 20 on a 90cm gun really too much power for a hole shot, even if you use the forward tab? Or is it more of an issue with longer guns?
