John - I like the combination very much, but I don't think it is significantly
better than other brake set-ups, and do not necessarily champion this set-up over others. I went this route because (a) I, too, felt bad leaving the QB brake stop bridge hanging out all alone, and (b) had another bike that was in need of only one Minimoto (a 92 XO1 calipered frame with a 93 XO1 canti'd fork) and after a parts shuffle across 3 (mostly) canti'd bikes, I ended up with one spare Minimoto.
I'll say that the Minimotos and Motolites have a sharper, crisper, more abrupt stopping action than the Touring and/or Neo Retros. That is not to say that the latter pair are 'bad' at stopping - they're marvelous and strong - but the transition feel is slower/smoother. When running a combo of Minimoto front + Touring rear, the difference in brake feel is not funny or weird or all that noticeable. I suppose there's slightly less wheel lock with the Touring out back, but this isn't a dominant factor for me.
I personally would recommend the Touring/Neo Retro for road riding; and Minimotos for more off-road/trail action, and/or/especially in cases where quick-hard-steep stopping is desired. I save my Motolites for my 26" dedicated trail bike.
Last item - aesthetically speaking (YMMV, don't @ me!)
Minimotos look sick with knobbies
Touring/Neo Retro look sick with knobbies
Touring/Neo Retro look sick with slicks
Minimotos look just ok with slicks, but sick with 45mm fenders + slicks
Everyone's got different brake feelings and experiences, these are mine, hope they help.
