I rushed both of the units at March. At both boards, it was all non-priors. In fact, of the 5 interviews I was invited to, there was only one prior from the squadron competing. However, if you want to go Guard, enlisting prior seems to get your foot in the door. (Guard seems to hire from within more so than the reserves) The good thing about graduating and then rushing units is that if it doesn't work out, you can go AD through OTS which is easier to get then the Guard/Reserves. There is also always the Navy and Marines if you are just looking to be a military pilot.
