Originally posted by Vendee I can understand that you might want a better looking strap but be assured that the "flimsy nylon one" is certainly strong enough for the lightweight GRIII. I've actually got a couple of nice leather hand straps that I used to use with my film cameras but I prefer the flimsy nylon strap on my GRIII because of it doesn't add any bulk to what is a very pocketable camera.
My fear is not knowing how well the cord is connected to the nylon strap. While the GRIII is a lightweight camera, how much stress will the strap hold with continued use? I'm a big fan of over-engineered products because they tend to last longer and won't fail as quickly as products made to fulfill adequate/usable standards.
