In America and Australia they all use pyramid leads and there surf can be very heavy ! They say they hold very well . I admit they won't be as good on a pendulum cast ..but for most my bassing I only use a overhead thump ! . Be quicker then fixing grips when you have a manic bit of action!! Plus losing them in rough ground will be lot better than keep ordering Gemini heads and tails .. I've ordered a 5 to 6 oz mold from America .more expensive then other moulds I've got but looking forward to trying this out ...
