We use a full 10 colors on our reels which we have 4, then to get away from having 6 or 7 set ups if only needing a 5 color we half hitch a rubber band to our releases and lead core which won't hurt, and we use a #8 spro swivel which is rated at 50# and a 12#fluoro. Leader and a 9/16 duo snap at the business end, the #8 spro will fit through the eyes of your rod and will fit through the line guides on your reel, so you can reel the fish right up to the net. We use lead core a lot and this method you will have the exact amount of lead core you need with only 4 set ups.
