I have found shorter is better, you can back off and see the buoy as you are ready to move off and retrieve.
I understand the longer rope to buoy, if you use one of those triangle stoppers..... but they are a pain when wanting to let more rope for dropping back etc..

Does anybody fancy mentioning that a flounder comp would have several fish to each competitor 20 yrs ago.... now this from the RNLI comp: "11 boats 27 anglers only one undersize flounder" Disgusting!! Rob
