Resonant heads

[John]

How often do you change them, and why? I'm looking at new batter heads
but don't want to spend extra on the resonants, however they are the
"stock" Pearl heads that have been on for over 15(?) years.

Change them. You will notice a difference. They do stretch out,
believe it or not.
A thin single ply will do the trick.

I've found that remos ambassador and diplomat keep a very nice tone for
decades if used as tom-tom bottom, as long as they are not tightened to
their limit. the largest the drum size, the lesser the effect of aging imho
Or at least i've never noticed any sgnificant difference between a 20 years
old ambassador bottom and a new one, while snare drum resonants tend to
loose their mechanical properties in a few years.
nevertheless, to prevent aging of heads, as I'm using ambassador clear for
both, batter and bottom, I usually move up the bottom when the batter is
exhausted, and place a new one on the bottom side
