Got the Open Comb C and D plates yesterday. Shaved with the C open comb this morning. Very nice! A lot more blade feel than the solid bar. Quite a bit more aggressive than the C solid bar plate as well. For reference I have the B, C, D and E solid bar plates. Been using the C and D mostly. D has been the pick for the last half dozen or so uses. So the C open comb is quite a bit more aggressive feeling to me than even the D solid bar. But still a smooth and super close shave. Love it.
