Depends what I'm flying.....
Cassutt - Warm summer day since I have no heater, no wind or maybe 5-10kts down the strip, sunny and lots of scattered puffy clouds to play in.
TriPacer - Windy, bumpy and Gusty crosswinds so I can give myself a bit of challenge....
C172 - Cool crisp winter night, climb up to 10k, turn the radio down and admire the view!
