The dual kit did come with another spool holder, but I sometimes print with plastic that comes on spools with smaller diameter holes and had already replaced my left spool holder with this thinner one: http://www.thingiverse.com/thing:150416 so I printed a second one of those and now have the thinner holder for both.

Seen the second spool mount in my kit.

Timing on my part will be weeks behind the leaders here
and foresee this going smoothly.

Wiper technology will undoubtedly have a major retraction like jimc's factory file for PET+.
Retraction does relieve some tendency to stop hot end drip, with the extra moment
biting into the filament even better.

Found out PET+ can use a little tension on the drive tightening nut, but moving
to abs, the drive has to be tightened more. PET is semi soft, abs is a lot harder material.
