I have personally given up on xtg & do two passes & touch-ups. Most of the time the passes are wtg & atg, but there are times I simply go atg x2.

With that being said, you have already shaved your face twice before that final atg pass on some tough whiskers. Lather up and then strop your razor a bit. I'm not sure what you have, but 20 passes on a linen or canvas & 20-30 on leather should help to tune up the blade to take care of that final atg pass & leave you bbs.

Good luck and as Lynn says...have fun.
