34007 is an old model and I've always doubted the integrity of the wire. I made some bendbacks a couple of seasons ago and was disturbed by how easily they bent in the vise.
Gamis are great. I've not been let down by SC15 yet and have had a couple of large fish run a lot of backing out. I also like Daiichi 2546 but have had a couple break on me. Maybe the problem Fred mentioned above?
When sight fishing, look over your shoulder from time to time, you never know who's behind you
