I have found that my GB shuttle 6.0 head is super bright. I am using a SWR Workingmans 2x10 with it at the moment. Someone was just selling a 2x12 Aguilar for a great price, don't have the coin at the moment. It pops up every few month, can't figure out why it isn't selling.
If I were, do what jlrush said. I definitely need to do it when I get my next cab....although, I have heard great things about the ACME lo-B2.
