Minor Shimmy Update
Just another minor data point: I discovered on my ride this past weekend that, if I grip the handlebars on the tops near the stem during a fast (~30mph) straight descent (Sausalito Lateral, down from the GGBridge into Sausalito for any locals) and go into somewhat of an aero tuck, I can get the bike to speed-wobble at will. Moving my hands to the hoods or the drops immediately stops it.
Kinda weird, kinda scary. Had me seriously lusting after alternate bikes again...

I think you need to get rid of all your fancy-shmancy short wheelbase bikes and pony up for a Big Dummy.
;^)
Believe me, "get rid of all" is a phrase that frequently rolls around in the noggin...
sucks to hear it Jim.
Oh, remember my shimmy problems on the Bob Jackson?
Turns out my fork crown is cracked. I don't know if that caused the incredible amounts of shimmy I got, or if the stress from the shimmying cracked the fork. So... I dont know what I'm going to do with that bike. Either try to get a replacement fork or part out the frame, sell it, and get a Surly Cross Check (which is what I really want to do).
Some people don't seem to mind the wobble, but I think it sucks.
Cracked crown? Ouch! Get the Cross Check. Or, perhaps, a Rawland...
