Coiling the entire 100ft of twinlead into about a 2ft dia coil

Coiling the coax shouldn't make a scrap of difference.

True for coax cable. However, coiling twinlead added 3dB in loss.
It's common practice to coil the excess cable rather than cut it. Not
a problem with coax, but potentially a bad idea with twinlead. Nobody
is going to coil 100ft of twinlead into a 2ft diameter coil, so the
3dB loss is probably worst case.
