M_Boats: M15 Mainsheet Cleat

Be absent quite awhile but started getting boat ready to start sailing again. I need to replace the mainsheet cam cleat setup and would like to reduce the profile of the original setup. Has anyone tried a Ronstan RF58 or similar? Does anyone know what is being used on the new boats? Also I have some interesting photos of my swelled centerboard but don't know where to post photos. Thanks kww707 M15 Sail 128
