I may buy a bug as another "adventure", and I'm worried about how much time it will take to master. I found this info on Morse Express's site - http://www.morsex.com/pubs/bugs.htm The conclusion is that dual-lever bugs could be easier to learn, coming from paddles, as there isn't any delay for dot dash transition. While the GHD dual-lever bug is described, I don't see one in their current line-up. I'm aware I1QOD makes a custom, dual-lever bug, which is designed to work at lower speeds. Where did you find a source for dual-lever bugs?
