I really didn't want this discussion to go to "why, or why I don't, like single triggers", though I DO appreciate all the answers thus far.

I can take 'em or leave 'em. I can switch from one to the other, and back, without a conscious thought. I have numerous singles and all work perfectly. Personal preferences aren't really what I'm looking for here, rather a direct comparison by an unbiased expert on the reliability of the various vintage designs. Probably doesn't exist, though.

May God bless America and those who defend her.
