Hello John, our situations look familiar. We both go for bbs with a final atg pass and we both have sensitive skin on one side of the neck and therefor sometimes irritation. So far, so good.
With a Super Speed I can't get bbs using Derbys or IP (Crystal). I like those blades and they give me a terrific bbs in both a Merkur and in a HD Rocket in two passes, wtg and atg - but my skin doesn't like this two days in a row.
I have tried Feathers in a Tech and today in the SS. In the Tech I could not get 100 percent bbs though I also did an atg pass.
In the SS today the Feather left the skin as smooth with an wtg and a xtg as the same blade did in the Tech with a wtg and an atg pass.
I have not tried to go atg with a Feather in a SS yet. But I will definitely use that combo in order to get a bbs with a SS.
I hope I haven't confused you totally with this long yada-yada? That was not my intention but this is as close as I can get trying to reach a conclusion today. Of course your skin, stubbles, and tecnique may differ a lot from mine. I look forward to read your next posts about your experiences.
