How long may the wires be?
10 to 20cm works well. Sometimes shorter is better, but the X220 shouldn't make you any trouble. So I'd rather choose cables that don't make handling of the clip too inconvenient.
Nico is right about convenience.
Still, I experienced inconsistent reads almost every time I used 20cm wires. (Yes, I checked the wires and the clip for resistivity or loose connections, etc.)
I experienced almost no inconsistent reads with 10cm wires.
When I shielded the 10cm wires with earthed aluminium foil, I got entirely consistent reads. Unfortunately, this is much less convenient to handle than unshielded 20cm leads.
Your luck may depend on how electrically noisy your environment is.
