I'm sorry guys that raised the dead from the dead old topic, just have a few interesting observations from personal experience, perhaps someone will need this information in the future.
Compound bows have a let off of any where from 65-80%. Guys who are shooting 70lbs with a compound with 80% let off are only holding 14lbs after the let off. Those same guys will not be nearly as accurate with a 60lb recurve or longbow.
There are sights for recurve bows but honestly for survival bow, stick to the KISS principal. The only thing that replaces practice & experience, is more practice & experience. Shooting a bow without sights is not nearly as difficult as you would think.
I had a 35lb fiberglass longbow
https://secretstorages.com/best-compound-bow/ for years (my wife inadvertently sold it during a garage sale - she's still is not allowed in the garage). I had a dozen wooden arrows for it and I was ridiculously accurate within 30 yards. Never shot it with anything other than field points though. Never shot broadheads with it.
Look on eBay and check Craigs list. You'll want a finger tab or glove for holding the string. I never used an arm guard because, IMO, it promotes the bad habit of locking out your arm when shooting.
