What trans. you running Ian? What brand converter did you have and what brand did you swap to? Another upgrade for my Cuda I plan soon is replacing the 727 with a more efficient 904 and have been looking at converters. Want to make sure and get a good one but am somewhat limited by money. Always great to hear someone swapped verts and made a huge gain and your gain sure was big. That's what's got me wondering what you had and what you went too.
