RE: What are some good sights to use
Putting it simple and sweet. Nothing made of plastic. Look for good machined metal construction. Steel pins or fiber supports. An adequate hood that protects that pin and fiber. Wrapped fiber pins if you need bright pins for those first and last minutes of hunting.
Something that doesn't need a battery operated light. The lights just run up the cost, and are usually too bright when you need to see your pins the most. Batteries can cost as much as $3 each and most lights use as many as three.
Stay with something solid. Cobra Sidewinder is a good start. HHA OL series are very good. VBG, Impact and others, too. Visit some websites to check out the lastest offerings.
One thing. If you are going to buy a sight made with any plastic then keep most of your money in your pocket and just buy a really cheap one. No more than about $25.
