Congrats on the new bow. What kind of arrows are you going to shoot? Wood? Aluminum? Carbon? I use to have a 45# Kodiak Hunter that I shot wood and aluminum out of. After shooting woodies, then shooting aluminums, I don't ever want to shoot aluminums again! They're way too noisy compared to woodies. Well made bows are pretty resiliant, so it'll take some serious beating to do so. It's a good idea to unstring it whenever you're not using it. However, when I had my Kodiak Hunter, I pretty much always left it strung. I shot about everday in my basement then, and usually multiple times a day. The stringer I had wasn't that great, so I just left it strung. It didn't hurt the bow at all. When I wasn't shooting I stuck it in the corner behind a tape case. It made it easy to grab the bow when I was bored and walk down to the basement and shoot. Like Lilhunter said, don't leave it in hot places, as in next to heat vents and such; especially if the bow is strung. Don't leave it in your car strung either when it's hot outside. If you take care of the bow, you won't have to worry about much, just inspect it every time you shoot for cracks and such. Hope you have a lot of fun with your bow.

God bless,
Brandan
