- what is the likely safety implication of flying above 15000 with a
TT21?

I suspect the answer is "none whatsoever".

The word "suspect" says that you don't know. I don't know either, but I
suspect that there's a reason for the requirement.

Frankly, I simply don't understand this discussion. The price difference
between the TT21 and the TT22 is negligible (list price at Cumulus
Soaring $2195 vs $2395). How would any mentally sane pilot choose to go
illegal for a price difference of just 200 bucks?
