where can you gentlemen purchase the strongest most durable bow strings, I purchased a half dozen strings when I bought the bow, and the last one just got too frayed , Id prefer to buy on line rather than go to the local archery shop, and I can,t find that older bow listed.
I've used an older jenning's unistar bow for 30 plus years
and while it may be an older heavy antique, its damn accurate and I have a hard time finding another 31" draw 80 lb bow that I've become very comfortable and familiar using

check with bow string depot. They build great strings sets

You will be limited on strength and durability with that bow. As the strings look like they will have to be made of Dacron. Do you know the length of your string.

you can try America's Best bow strings.
