I think I'll follow your lead and convert them to measure in pie. The only question now is Cherry or Apple

Nah...convert to pie and everybody'll want a slice. Then you're left with a couple measley radians (crumbs) and a mess in the kitchen to boot.
Go with the non-reals. Anytime the conversion involves negating negative roots and the quadratic formula people's eyes glaze over and they mumble something about needing to rotate their tires before the next heat. At that point you're so far inside thier heads that you own 'em on the track. If you offer to derive the quadratic formula (or even identify the descriminant) they will run from the building shrieking in terror.
Algebra seems to have had a traumatic effect on some racer's childhoods.
