Chuck:

I agree.  I also live in the deep south where it's HOT.  Staying at altitude as long as possible is more comfortable.  I can descend quickly and the cabin will still be cooler than the OAT when I'm back at the hangar!

The idea that going to idle at high altitudes will induce shock cooling

quotient to it.  But there is a very good reason not to descend like a
rock--efficiency.

To gain that altitude, it took a lot of time, gas and loss of airspeed.
A cruise descent gains back time, gas and airspeed.  A mass at altitude
is stored energy; use it.  Don't fritter it away by chopping power and
dropping into the pattern or approach.  Granted, ATC may not always
cooperate but never hurts to ask.

In smooth air, let Vne set your power.
