Is an amp that fails at one minute with 100w FM
better matched than an amp that fails at two minutes
with 100w CW?

No, you've got the concept backwards. Obviously the worst matched is the
1 o=minute case, next would be the 2 minute case and so on up to one which
runs for about its MTBF at the connected load. This last case would
likely be the one the designer was targeting.

It's been thirty years since I "hammed". I was only interested in the
electronics, not the talking, so I dropped out after I got a homemade
solid-state 2-meter rig running.

I did the same after putting together a HF setup. The electronics was fun,
but the chirping was booorrring.

But I vaguely recall a 5/8 wavelength antenna that had a good low-angle
pattern.

I didn't know the height affected the pattern that much. IIRC 5/8
wavelength seems to be what the AM stations around here. Though they'd
load up a barn if it worked.
