Mike,
>> I would talk to sailors and not compare numbers in a catalog.<<
Problem is, I haven't found anyone yet who's had the experience with the PX cleat on a cat, so I have nothing to compare but the specs.
A lot of sailors on other boats seem to love the PX cleat. Real easy to cleat and uncleat. You don't have to pull the sheet while lifting to get the cleat engaged. You just lift up. To release, a flick of the sheet (same as with a cam cleat).
Before switching over, however, I was hoping to hear if any cat sailors have had experience with them, good or bad.
