You've got 3 buttons at the front of the throttle, so why not use 'em?
Assign the normal level snap-views to the throttle's POV-hat (with the orientation you prefer), and use 1 of these buttons as "up"- and another as "down"-modifier - this way you can shift any view up or down any time you need to, and you can look straight up even without using the POV-coolie at all. (This works with any programmable/mappable controller - TM, CH, Saitek, etc.).
If you don't have a TrackIR, you could set up the throttle's microstick to control the mouse-look/panning in addition to this - 1 thumb for 2 choices

, and all the view-control you need at the tip of just one single finger

.
@FOGOLD:
Would you believe

? CH sent me a couple of their controllers

to get a better impression than my pure theoretical guesstimation

... and I fell in love

! (It was harder to (re-)learn what this word "support" means

than to actually get into Bob's scripting

...)
