C903 I can see that you're the kind of person that just can't let things go aren't you. You ask what's necessary well if you want to go that far non of the modern era archery equipment is necessary, but I bet that you still shoot a compound don't you. It's like everything else ,do I need 77 channels on my TV, do I need air conditioning in my house and the list could go on for ever. All of these things are luxuries not necessities. So I guess my answer to your question is no these things aren't necessary but if I can blow a 3 inch whole through a deer instead of a 1.5 inch whole why not.
