+1. I usually do two XTG passes under my nose (for me, this is one going ear-to-nose and one going nose-to-ear) instead of trying to go WTG or ATG."I love the end result of a shave with a SE, but my problem is under the nose - can't get there..."
For me the under nose portion of the shave is handled effectively with the XTG pass. Start real easy and sort of chip away at it until it's all gone.
