The whole gear your Fixed side higher than your freewheel side is kind of silly unless you live in a super hilly area, in which case I would personally run SS or get a geared bike.

Ive been running a 46t front, and the 17/19 dingleberry rear. Ive primarily been riding the 17t, but I find that that is really alot of gear inches to be running on flat ground, since I find myself mashing around all the time, instead of spinning at a higher rpm..having bad knees this is kind of getting old:/ That might also be a good solution to the gear dillema.
