You refer to getting commissioned as "plan A" so is that not still the case? It can still be your primary goal even if you had to adjust the timing a little. I know the thought of going back to OCS sucks it hard. I broke a couple of bones and got to spend a second summer in Quantico, but in the end it was worth it.
As far as being a reservist, don't be fooled, you can still be deployed or sent on an IA. So if doing the "traditional" reserve thing is what you're after, you might be surprised. The upside to enlisting as a reservist is that you know exactly which MOS and duty station you'll get once you finish training...which for some aviation MOSs could be 1-2 years after you leave for boot camp. Any reserve centers close to you?
