I would say a 6/8. But that is my opinion.
I own razors in 3 sizes - 5/8, 6/8 and 7/8.
I have a mustache, so I can't give any
advise on shaving under the nose.

Excluding the area under the nose, I couldn't
honestly recommend one size over the other.
If the razor is SHAVE READY, it will do the job.

Hope this helps,


Terry
