Get the best of both world, an adjustable sight.
I just picked up a Truglo rover, and I' m in love.
I shoot a pretty fast bow and have used 1 pin at 25 yards, it allowed me to shoot out to 30 with minimal compendation, all I really had to do was hold a few inches low if the deer was under 10 yards. My problem was I like to practice out to 50, and like the confidence of tighter groups than holding high with 1 pin gave me.
I never wanted more than 1 pin for hunting, too cluttered and a chance of picking the wrong one. With the adjustable, I can practice all I want, and then lock it in for 25 when I go hunting. If it' s real thick with no long shots, I think I' ll be locking it at 15yds, but 25yds should be Ok for most occasions, If I see a deer at 40 yards, I can just slide the sight to 40yds and aim dead on. Any deer shot at that far has to be ranged anyway, for me, so taking the 2 seconds to adjust the sight shouldn' t be a problem.
Otherwise you can buy a sight with 3 or more pins and take your time and figure out how many you prefer over the spring and summer, don' t make a decision like that based on other' s preferences. You have plenty of time to decide for yourself what fits your setup and style.
