Quick question for the group.

I'm currently out on LOA from Mesa for about a year , but I'm working as sim instructor at ATP/Higher Power. I do about 80 hours of instruction in the sim a month and I recently got typed in the 737 about 3 months ago. I'm looking to get back but I really can't afford to go back to Mesa at this point. So my question is, yes, I haven't physically flown an airplane in about 12 months, but I've been actively teaching in the 737 for the past 3 month and prior
To that the EMB and the CRJ for 9 months. Do I need to go back to actively flying for a bit to be competitive for a call at Spirit?

Quals are:

4700 TT
2600 TURBINE 121
0 TPIC
EMB 145, CL65, B737NG
Bachelors, some Masters classes
