how many slots would that leave me and what could/should I fill them with?
Just get a regular Spirit... Its blade is partially serrated and a different shape than the CT one so it's not redundant, and the bottle opener doubles as a prybar of sorts so that's ok as well. You only get duplication in the scissors and can opener, but the former is also a different beast than the regular Vic scissors (and seems more heavy-duty), which only leaves it down to the can opener. Fine by me...
Maybe this could help a bit: Click.
You should start with a S62. All you would need to buy would be the wirestrippers and another flathead.
