<><> However, it was way easier to blow [snip] comparison of the two
bores show that the plastic model is smaller. I would have guess
differently. What other factors would be involved?

A clarinet is not a perfect cylinder. The amount & location of changes
in diameter affect resistance. So do the precise location & size and
undercutting of tone holes, the amount & type of barrel's taper, and
details of the mouthpiece. All of these things interact with each
other, and they affect timbre or 'character of sound' as well.
Resistance also varies between individual instruments of the same model
and manufacturer, which shows that very minor differences can have
noticeable effects.

and of course, if one of the two instruments that you compared has a
minor leak, this can make a huge difference in 'resistance' even though
both are playable.

People argue as to whether high resistance is good or bad. Variations
in resistance are accompanied by differences in timbre or 'character of
sound'.
