I've just upgraded my new HE3D sky to dual extruders, but I seem to have a huge drool problem (or at least my printer has).

My biggest concern is the white line above the 'B'. It is fused into the green, and I really only want green there!
I could live with the furry bits if I had to... they're easy enough to scrape off. But I suspect that they're another symptom of whatever is causing the blobs on the surface... probably furry bits that have got trapped during green extrusion.
I'm not particularly concerned about the under-extrusion in the white region... I think that's just bad geometry in the position of spool and extruder. And the break in the model at the bottom of the white rectangle is I think because the printer tried to home to [0,0,0] after the print, right through the middle of the model.
In case it's relevant, the white extruder is 18mm to the left of the green one, both printing PLA at 210C, and standby temperature is 175C (the default). I already have 6mm retraction, and I'm reluctant to go higher with that in case of jams. The model itself has 0.8mm thick walls, with some reinforcing inside. Sliced with the latest version of Cura.
Can someone who has dual extruders please give me some pointers? Should I maybe lower the standby temperature? Would Cura's "ooze shield" correct this?
