I wonder if having your hands
FIRMLY in the drops didn't contribute to the wobble problem. Keeping your arms and elbows rigid and stiff can exacerbate the wobble. I've notice on a local 40+ mph downhill on all of my bikes (56 and 57 cm frames) that I can generate a bit of instability by locking my arms and it goes away completely when I relax a bit.
Yes, large frames are not as shimmy-free as small ones but the current use of oversize tubes and very stiff frame designs has greatly reduced the tendency.
