I'm not going to try to sway you from hunting pronghorn if that's what you want to do, but in my limited experience there is a great deal of difference between a 1 point unit and a 2-3 point unit, primarily being the amount of land available to access. I've hunted 2 units that can now be drawn with one point, and although if you worked hard you could kill a 'lope, it wasn't the "real" western experience you're probably hoping for. This year, I'm hunting an area that took 2 points in the regular draw, and there is way more accessible land in good antelope-type country than we could possibly look over in a week.
My preference would be to hold off another year or 2 for a better quality hunt.
IMO, the better experience for next year would be a deer or even elk hunt, even if it's just for cows. Of course there's the probability that out of 4 hunters, not everyone will fill a tag, but that's a real possibility in some of the easy draw pronghorn areas also.
Good luck whatever you end up deciding.
