Sorry - one more vote from me to NOT wear a leash with a twin tip. El Rudo points out everything anyone really needs to know…
A good solution if you just want that extra chance of retrieval before a wave takes your board is to tie a length of bright colour webbing to it, like a 2-3ft lanyard. Let it trail off of the board.
When you come off and are just inches from grabbing your board, you can usually grab the lanyard. Granted, this works better for surfboards as they tend to head away from you nose first and you tie it to the leash plug at the tail, but it would offer some use on a Mako I reckon. Unlike a leash, it offers no ‘boom’ like drag in the water (GoJoe doesn’t cause drag either for that matter).
