Completed several builds with Dunlop 6130 wire.  Nice, but a pain to set in an 0.022" slot without glue, rather skip that whole extra set of steps.  Just tried a test with 6170, with an oversized (0.024") tang.  Fretting has just gone from 22 shots of aggravation to pure joy.  What's the standard wire that everyone in CBGs tends to favor?
