So I've been wanting to mess around with a single pin for awhile but didn't wanna drop a lot of coin on one. I'm amazed at how much more accurate I am, however, is an HHA sight durable and easy enough to use to rely upon in the mountains, seems like the slider option is a pain to try to move and adjust in a hurry and the sight tape marks are really only good in 5 yard increments. Does anyone successfully use one of these to hunt mule deer and elk with? Do you make a custom sight tape? Do you leave the slider unlocked for quick adjustments? I ask because I think I'm sold on the single pin idea, I just don't know if the HHA 5019 slider is the best bang for my buck since I have several other large purchases I'd like to make in the near future that I think are more important (pack and boots specifically)
