So the Game Changer .68
First I had the SB plate. I bought it used. It's a nice mild shaver but there seems to be something wrong with mine as the two sides sound and feel different. One side is much smoother than the other ATG.
I got the .68 OC base plate. What a shaver. Fantastic. A tad more efficient than the SB maybe but much smoother. Anyone who like a Tech or 34C shave or similar, and wants a SS razor, should try the .68 OC. It clamps the blade better than the SB, but also bare in mind my SB seemed a bit off somehow. I'd rate the .68 OC as one of my all time favourite razors, and I like razors on the milder side. It is just....great.
I have the JAWS base plate coming my way as we speak. Opinions to follow. Had my first shave this morning with a ATT S1 and found it a bit rough ATG. We shall see. I shall persevere with it. It certainly didn't blow my socks off like the .68 OC, although the end result was as good.
My benchmark is how comfortable I can shave ATG. Especially those bits we all have that are guaranteed to cause a problem, or hurt a bit, if the razor isn't top notch. That means top notch for my face.
I also like mild razors, and with a sharp blade work best for me. The GC SB .68 is the best I've ever used, I've been choosing it over all my other razors, and now only use my Rockwell 6S occasionally now. I'll definitely be getting the open comb version as soon as they are back in stock.
I think there may be something not right with your SB plate, mine doesn't feel the way you've explained yours does, and the blades are clamped down very well in mine.
Even though this razor is very mild, I find it to be very efficient with good sharp blades, and even with 4 days of growth I can get a BBS shave without any problems, even with my old person tough beard.
I usually don't shave every day, but I wanted to test this one to see how it would work as a daily shaver. My results after 30 straight days of shaving were great.
