It has probably been asked but I can't find anything. I'm looking for feedback from the hunters using a single pin with power scopes. Are the scopes used for target shooting only, or are you guys using lenses for hunting? What are the benefits. I'm ready to spend some money and I'm trying to check all options. Im looking at the Fast Eddie and the HHA Kingpin. My eyes are getting a little weaker, so I was thinking a lens might help tremendously. Concerns are what happens on a rainy day, cold day, sunny day. Will a lens help but give opportunities for failure in certain conditions?
