marine,

Absolutely you can... If you've got enough common sense to make it through Marine boot, changing a string is no big deal!

And... After finally starting to use quality strings myself this past year, I can honestly say that every archer owes it to himself to buy a nice after-market set and replace the junk that most companies put on their bows.

BowTech is one of the few I know who put after-market quality strings on the bows they sell, and I've heard good things about the strings on the new Switchback XT; before that model came out, you probably couldn't have bought worse strings from a manufacturer. That's not bashing; that's experience. I shot them for six years.
