Hey John,
'Haven't seen any other Cruz riders yet, but I suspect its a little like searching for intelligent life on other planets; it's as much to do with looking at the right time as it is the right place. ; )
I'm up to my fifth of sixth ride since buying the bike, and it's feeling good. the speed wobbles at high speed are lessening, as is the random 'swerving'. I feel pretty confident that these will disappear completely in time.
I still have problems starting on an incline... Today I discovered that's partly because I keep starting from too high a gear (i.e. the middle gear range). Provided I plan far enough ahead to be in a low gear when I start I generally do okay. Still crapping out on the steep inclines though.
Can't really complain; I'd have the same problems on a regular bike - the difference is with a reg bike I'd do a better job balancing, mainly by twisting the handlebars left and right.
I stumbled upon a similar sensation this morning with the Quest. Will take a fair amount of practice to master methinks.
Speaking of handlebars, the rubber grips are still slipping a bit - the right grip in particular managed to loosen my side mirror (and it fell off). Not a real loss as it wasn't working well anyway (better suited to a normal bike). 'picked up a Mirrcycle mirror today in my lunch break. Will see how it does.
Will also try the hairspray trick to hold the grip in place.
Sidebar: While in the shop I noticed a Toppeak rear-rack bag that had side pockets that expanded into pannier style L-R bags. Looked awesome, but at $150... I'll have to stick with rolling up my work clothes for the time being. : )
In terms of my back, the Quest has been great. The bike lets me ride gently, concentrate on engaging my glute muscles while supporting my spine. Being able to ride to work again is... Awesome.
Places I'm still having alot of trouble in: fiddly cornering on inclines (in any gear) and quickly changing down in gear to prepare for said fiddly, inclined corners.
The example is the old Entertainment centre bridge. If anyone on a Cruzbike can navigate over that bloody thing... Well, I'm throwing down the gauntlet and issuing a challenge. : )
