Collector or not, my ishiwata 022 - if seamed - rb2 rode like a dam noodle. Thing would get crossed up descendanding and insist on drifting out of the lane above 25

Meh

Ishiwata 022 is seamless, identical material and process as
015, 017, 019; differing only in thickness.

And seamed tubing shouldn't generate any "dam noodle" effect. It would impose a slight weight penalty, but it
shouldn't affect the rigidity of the frame, if that was what was meant. If anything, I'd expect seamed tubes to be
a bit more rigid than similar seamless tubes of like diameter.

Could we discuss what might actually generate the handling behavior Doug describes? Or would that be too
on-topic for this group?

Low tire pressure, unusual placement of rider or cargo or
both, head angle and or fork changed from crash, slack spoke
tension among other things.

I had virtually every model of the Bridgestones since two of the best bicycle shops in the area owned by the best mechanics carried them. I found them to be very capable bikes though a little too heavy in my opinion,

That was probably from the wheels. My 1 and 2 rode pretty much the same.
