Make your own
Get a block of wood 3'X 4". Round off the corners. Round off the edges on the top side and make a grove along the center big enough for two passes of 1/4" line on the bottom side along the 4" axis. Make a grove in one of the 3" sides deep enough to hold 1- 1/4" line. Finish it off nice and pretty. Take about a 24" length of 1/4" line and tie a not in each end. Put the knots on the end that you made the grove in and run the lines down the grove on the bottom. You should now have a loop on the end that did not get groved. 5200 the whole thing where ever you want to have a line.To use, coil the line, reach through the middle of the coil grab the loop and pull it through and attach it to the grove on the 3" end.Takes me about 15 minutes to make one with a router and and hour or two to finish it out.
