Another question on this topic, the e3d cyclops 2in1out with 1 nozzle is described as switching not mixing, so is the junction between the two filament paths in the heatbreak or heater block? If it's in the heater block why isn't this considered a mixing hotend?

@DjDemonD - Yes I totally agree about clear descriptions. Although not sure much value or credence can be taken from ebay adverts as to the veracity or accuracy of their descriptions. After all they are the ones that gave us the all metal JHead
When you have a 2in1 mixer like a Cyclops, the ability to extrude from both sides at once is not down to the hotend itself, but more the simultaneous control of the 2 (or more) extruder motors, ie 2into1 ala mixer. The degree to which they do or dont blend is design related but principle design objective is the same. This is opposite of the Y splitter where loosely speaking, only one motor/filament can be driven at any time. In other words, pull one out before the other can go in.
or maybe its just the way my brain is wired

Well maybe they just aren't that popular. When it comes to multi-colour printing its hard not conclude its quite a lot of trouble, and a pot of paint and a brush afterwards might be easier. I gave the y splitter a go but wrestling the firmware and slicer to produce the right output, then adding in wipe and prime towers etc.. was just too much trouble for me, as I mostly print mechanical parts and rarely print "art" objects.
I can see the point to having multi-material for support/print or different materials for perimeters and infill. But then it seems the most satisfactory, but by no means cheapest way, to do this is with dual x carriages, with independent z-probes to ensure no nozzle level issues.

@ Origamib - When I say y-splitter I refer explicitly to those single (standard) nozzle setups, which in fact doesnt even refer to the hotend, but the setup configuration, where there is a distinctly Y shaped splitter supporting two filaments that are fed one at a time.
OR are we sayiung the same thing. A hotend with a Y split in the cold end? That would be in my book a Y splitter. Split in the hot zone (or capability to run both filaments at same time) thats a mixer.
@DjDemonD - perhaps no one has made it easy for users yet, I agree dual filament printing is a PITA with current tool chains. I think Deckingman has taken this forward to some degree with his efforts.

IMHO the Y-splitter is in the heatsink and the hotend is the silicon covered round piece. It is connected by a classic 6mm stainless screw. Hard to imagine they squeezed two PTFE tubes in there to meet in the hotend?!Quote

The splitter path maybe have two sharp corners but they're in the heater block so they're not handling solid filament.
