Well after the first shave I have to say: wow was that a harsh shave! Used a Personna Lab Blue second use. A super close good shave but not as comfortable as the regular Flexi. Need to pay attention using this one. I think I had it set too high for me. I use my SB Flexi on 3.5 so I started at 3.5 on the OC. I did the WTG pass on 3.5 and it was more blade feel and closer than the SB. I had to turn it down to 3 and finally to 2.5 for ATG sideways on my neck. I find the SB flexi shaves best for me at neutral to riding the cap some, but this OC not as shallow. I did get a very close BBS shave but the alum bar lit me up. Next time I'll just start at 2.5 and it should be more comfortable. It's no Fatboy that's for sure. I use my vintage Gillette adjustables at 7 and could run them at 9 and still be a comfortable BBS shave. I realize the number settings aren't a direct comparison, but I'm comparing the comfort and end results. Maybe the Flexi OC isn't a good choice for daily shaving for me, but I'll try it again turned down. So far I prefer the SB Flexi over the open comb. One use isn't a good trial. Anyone who can shave with this on 6 must have a face of steel haha!
