I prefer the normalized version of the connection myself because this allows to easily dis-connect the VCO from the bus when wanted. I often do this when using the Buss Access modules on a cabinet with more than one "receiver" from the bus. Often a situation will come up where you want to NOT have the VCO transposed by another signal on the bus. It also adds to some confusion when you have a VCO changing pitch (from the bus) when you are doing it from another module and forget about the normalization. I would probably not use the built in connection and make a separate one through the normalized jacks myself. I understand doing this on modules that only have one front panel CV in like the A-111-5 though, Doing this allows it to have 2 CV ins when normally it doesn't. Not much room to add a jack there.
