i play live exclusively and beat every game but PLO. have been messing with vision a little bit and my preflop is first leak obviously.

is vision best route for tuning this or is there course\literature out to be able to evaluate hands quickly. wish propokertools was up again could get some basics from their lists.

not looking for 18% from middle position, looking for method of defining 18%. in quick search here didn't find thread.

any help appreciated.

thanks, clint
