Your chances would be better for a cow in 55. I would keep that tag. They'll be herded up by rifle season, so you're not looking for a single animal.
I can't give you any specific areas in 55, because I don't hunt OTC units. I live and hunt in 481 right next to 55. During the day the elk will be bedding down in the timber. It's my style to go in after them with still hunting. I don't recommend it unless you have some experience in that style of hunting.
You need to catch them feeding, or going back and forth from the feeding and bedding areas. This will be at first and last light. The problem with finding where they are by scouting is it all changes once the elk are pressured by hunters. Do your best to be up high before daylight, and see if you can find them feeding in meadows. Then try to sneak up close enough for a shot. (spot and stalk)
Elk hunting is never easy, but a DIY hunt on an OTC public land unit is even harder.
