A 44mm FPJ Linesport has no lugs, so it may wear similar to a 40mm watch with lugs. My 6"/154mm wrist is a bit smaller than yours, so on traditional watches with lugs, I always go with a smaller (38-40mm) case diameter if I have the option. That's why I'd get the 40mm Optimum. But as others have said, you really do have to try it for yourself.
