I would save my points. Those later seasons can be tough when those big bulls leave the herds and head off by themselves. If you do not know the unit well enough (due to all the private) it can be tough finding them. I myself have been searching out new areas and debating on doing a late season hunt. I don't have enough points for first rifle yet so I have been trying to find where the true giants go to hide after the rut is over.
I can help you out some with certain areas if you PM me if you would like, but those later seasons you have to deal with more hunters (both elk and deer) and the critters are quite pressured and most will be on the private by then.
2nd season has never been my favorite. This used to be the longest season, but now with 3rd being nine days long more people may hunt 3rd season now. I always liked 1st season for elk and 3rd season for deer, but the deer tags for unit 40 are taking 1-2 PP's for 2nd and 2-3 for 3rd.
You may have better chance at a decent bull during 2nd due to the herds still being together, but it is always hard to tell. I hunted 4th season with a cow tag in unit 40 in 2000 and blew my chance on a cow (the only cow I saw all week) opening morning and I seen 6 bulls in 5 days. It was a tough hunt that season with the bulk of the elk staying in Utah on the west end. I also hunted the east end on the forth day and did not find any sign. I have found elk in the wierdest places since then, but it is no different in 40 than in my OTC unit, and by looking at the pic of your bull you guys know where to find them (down low).
I will probably hold out until I can draw a 1st season tag. Good luck with your decision and PM me if you decide what you are going to do and have any specific questions.
Out here in Colorado, and in the units that I haunt, it is a tricky game to figure out how far to pack in on a rifle hunt. You want to get away from the masses that have moved game away from the roads but might want to stay close enough that you are taking advantage of the animals forced movements. There is no universal distance but I like the 1.5 to 4 mile range for day hunts where I am not planning on bivying out. This keeps you in that productive buffer zone where the animals are really...
