In SLC you will be on reserve between IOE and when the next bid cycle begins. You might or might not be on reserve the first month that you bid, after that you should be a line-holder (for the near future anyway).

Bidding closes at 0900 on the 17th of each month. If you are done with IOE or almost done with IOE prior to the 17th, the computer should let you bid...get in and attempt to bid while on IOE, you might save yourslef a month of reserve.
