I have the 405's and I do like the lighter color but CXL is pretty awesome as well. But since I already have the 405, getting a 403 doesn't make sense. If I get another Indy boot, it'll probably be a #8 with a leather sole.
Also, I guess I'll be differnt in regards to the hand-stitched vs machine-stitched. I prefer the subtlety of the machine-stitched boot.
