I think rolling your points every 3 years is a good idea. If you watch the trends in the pronghorn populations, you can put yourself in a good unit with 1-3 points most years. The number of units that you can actually draw on a second choice that are decent is largely drying up. Its turning into a first choice game if you want to hunt for sure. I think its even a better idea to only collect a point or two at most and hunt every year or every other year.
I drew this unit on a third choice last year as a Resident and shot this buck:
A friend from Arizona drew the same area as a NR last year, his 14th in a row. He likes to hunt and not collect points...cant blame him for that.
Both bucks in my garage:
