I realised you need actual specific cable to connect a head and cab, rather than a standard guitar jack lead.

I haven't done this yet anyway but am buying a cab for my head.

Will these be OK for it...?

Its my local shop and am testing it tomorrow.

As long as it's definitely a speaker cable and not an instrument cable, you'll be fine. Both of those will work, except I personally would avoid the Stagg. Their quality is inconsistent, in my experience.

Yeah, they should be fine. Personally, I make my own out of mains extension leads but either of those should do the trick.
