Just a few points to consider. In your original post you mentioned that the terrain was thick and hard to get bow shots. That's exactly the kind of terrain you're going to find elk that have seen any sort of pressure in pretty much any unit/state. As others have said, the fact that you even got in to bow range on your first hunt is a heck of an accomplishment. I killed my first bull in 1st rifle in 42 years back. My buddy went back a few years ago for archery and came back completely skunked, so well done. I'd have to agree with what others have said, learning a unit seems to be the greatest variable you can affect to increase your success. That being said, it seems like you have a decent understanding of the western point structures, but just wanted to make sure you're aware that if you don't apply for an actual license in Montana (not just preference point later in the year) at least every other year, you will forfeit your PP. So be sure to pay attention to that if you'd prefer not to lose the $200 you already have invested there.
And again, as others have said, in Montana you're going to have grizz to tend with. Depending on where you're going, they may not be as bold and aggressive as around the parks, but they will likely find your kill if you leave it, and if you're solo, you're going to be leaving it. So make safe choices about the solo thing.
Cheers
