Welcome aboard James! I know exactly what your talking about. When you use heavy mono it tends to unraffle on the reel. Try using braided line and you will not have this problem. To put it on use an Arbor Knot.
1. Thread the line around reel.
2. Tie an overhand knot around the line itself. Then just tie a second overhand knot in the tag end. This second knot keeps line from slipping through the first.
3. Grab on either side of the knots and pull tight. Cut off the excess. Then slide the first overhand knot down the line to snug it around the reel arbor.

If your to busy to fish, then your to dam busy!
