Single wiring will be fine, just use cable jumpers, and you needn't spend a fortune on this stuff. Read up a little on resistance and capacitance of wires, which I barely understand, but can appreciate a simple explanation (see Roger Russell's site, or the excellent Blue Jeans Cable from the US) and check out some 18AWG wire - no thinner - and at the most spend about a fiver a metre.
That's my advice, based on the experience that spending more in my time hasn't resulted in an improvement, or more accurately, the cheap wires I'm using perform as well as the more expensive ones. YMMV.
