Is that the stock bear string that came on the bow?
if so, learn how to shoot with it but dont tune it just yet. When you are ready, go on ebay and look up a dude named “stilldub”. If that is a newer model kodiak which it looks to be, order you a new d-97 string.
he has a ton of options and is very reasonable on price. Great strings! Keep the stock string as a backup.
Beaver fur, rabbit fur, wool yarn, cat whiskers, all do a great job at dampening vibration. There are a ton of videos on youtube on how to install. I personally make my own wool puffs. Cheap and easy. Very satisfactory.
great bow! Keep slingin
