[time-nuts] HP10811 taxonomy?

[Richard (Rick) Karlquist]

It is entirely possible that a 10544 could have excellent aging and beat
a 10811.  The SC cut doesn't improve aging.  The other "disadvantages"
of the 10544 in terms of electronics also don't affect aging.  The
main advantage of the 10811 is that it is much better from a cold start
in an instrument.  Not something that affects time-nuts users.

I own several 10544As and have experience with perhaps several dozen others, and think very highly of them, but haven't seen enough 10811s for a meaningful comparison ("meaningful" being a relative term, when the sample sizes are as low as dozens).  What have others observed?
