I just saw and reserved a 23c to pick up next fri. Couldn't let it go after seeing it in a real-world shop in Glasgow. Been using only Gillettes for the last few months and have been missing my HD like mad. Anyway I've been all the way back to page 39 on this subforum and was surprised to learn the gap's the same as the Tech/ HD Rocket, but there's not too much discussion about it. Does anyone know how this differs in-use from a Tech/Rocket?
