How long are string loops(tied) good for?

[Raxxmaster]

What kind of signs in wear should I be looking for in a string loop.?

Watch for fraying at the middle, where your release jaws will wearon it,and at the bases of the knots. Keepthe loopwell waxed with plain ol' bowstring wax and it'll last a long time, but I would recommend replacing it each year a couple of weeks before opening day of bow season. It's not something you want to have break on you unexpectedly while drawing down on Mr. Big.

I shoot alot, and for $1.30 I replace it every 2 months.
