Wally, I love the set-up you've got there, especially up front. *I wish I 
was a little bit taller...*

Minh, I've owned a QB for 5 or 6 years. I recently traded my Orange 54 for 
a better-fitting, but less-fast ;) Silver 56. 

The 54 always had a front basket on a small Campee rack. I camped and 
erranded a lot on this bike, plenty of long rides in-between - it was my 
only bike for some time. I never experienced wobble nor shimmy, and really 
pushed the limits on load weight - in fact, the fork crown stay of the rack 
broke (not at the weld, mind you) on a mostly off-road 2-nighter around the 
Santa Cruz Mountains in CA, catastrophe gratefully/luckily avoided. It was 
fixed by listmember David Parsons. Since then, I've been much more careful 
with how much weight I add on that rack. Anyway, steering generally always 
felt totally great.

The 56 is more of a French fit, and it currently holds a Swift rando bag. 
It's fendered, and its main purpose is a wet-conditions SS road/rando bike. 
I have a commuter now that does the errand haul with a sturdier rack, so 
the QB's load stays light; only gets what I need for a day's ride. I'm 
currently in the middle of a bike-parts-switch-up, and it may end up 
getting moustache bars (I was recently surprised to learn I love them), and 
an Erlen rack + small Fabio out back. I've never ridden with rear weight on 
the QB, and would like to try it out, as others have recommended. I have 
tried rear weight on various other bikes, most recently a '92 XO-1, and 
have never liked the feel. 

The other main thing to consider with a large handlebar bag, besides your 
bar width as Joe pointed out, is how high your bars are in relation to you 
front wheel, and how/if the bag is supported. Yours looks fine in the 
photo, but something to consider. Once a week or so I try to commute 33 
miles each way to work on the XO-1. I use the small Fabio's, supported by a 
homemade "Pec-Dec". It holds just my laptop, charger, clothes, snacks, 
journal, few toiletries, other small incidentals (read: junk). It could fit 
more, and even with weight, the bag feels sturdy, the steering different 
but comfortable, smooth, responsive. But the bag, even with the support, 
just barely clears enough when stuffed with stuff. I need longer struts.

Anyway, hope that's all helpful.
