Impedance Question

I'm about to buy a Celestion Fullback to put in a cab I have and run a big old Red Knob Twin head through it. The amp has an impedance selctor switch which is very handy, so doesn't really matter if the speaker is 8 or 16 ohm, which are the options I have available. I also own a 68 Custom Vibrolux which is 2x10 at 4ohms. I'll probably never do it, but I could run the Celestion at 8ohms into the extension which is in parallel for a 2.8 something load, or a 16ohm which would be 3.2 something, assuming the speaker impedances are fairly accurate? Both below the amps 4ohms I know. I also know that the internal 10's will draw more power, but the Fullback is a couple of db more efficient than the G10 Gold and 1028k that are paired in the CVR, it's also a 15. I can't find a Weber z-matcher type product here in the UK, so reluctant to try it at all, but I'd be ok running an 8ohm load into the CVR would I not? (with the internal speakers disconnected). Seems like I should buy the 8 ohm version ?
