nuther vote for a single pin adjustable. I have one of the lower priced models from cabelas and it works great. I have been using one pin for awhile now but went to a one pin adjustable last year, nothing better in my opinion. With a range finder and some practice you'll impress your friends, unlimited yardage adjustment. mine is marked at 20-25-30-35-40-45-50-55-60 yds. But hunting I pretty much leave it at 25 yds.
