Looking for anyone who has real world experience rowing a Willie with, and without the UHMW Shoe. I've owned/rowed a few Willies with Gluv-it/Coat it bottoms. Looking at their UHMW Shoe bottoms, it appears there is a large alumuinum rib/lip holding the shoe in place. If you've rowed one of these, can you feel a difference in tracking? Pulling plugs etc? Looks like a big water catcher to me. Thank you.
