Welcome to the open comb club! Open combs come across as being pretty scary but once you jump in with that first shave it's smooth shaving from then on. Every once in a while I'll take a few shaves with a Super Speed or a Slim adjustable, but I always come back to my open comb. I haven't tried any of the modern OC razors so I can't speak to the quality of shave they offer - maybe someday when RAD kicks in again (I have a feeling that may be sooner than expected). You won't go wrong with a vintage Gillette OC.
