Best hot-end for fast printing?

Hello,

I want to buy a good hot-end for fast printing for 1.75mm filament and +-0.4mm nozzle.
Am I correct if I'm looking only for hot-ends which have a long heating length?
I also want to be able to print Nylon with this, so high temperatures are also a must!

I found the pico hot-end; it has a long heating area which should help for fast printing. However it seems to be quite expensive.
The E3D volcano hot-end also seems promising but it's nozzles only go as small as 0.6mm
Any ideas?

What do you mean by "fast" - have you a speed in mind?

Try the E3D V6 nozzles go from 0.25 up to 0.8 and with a thermocouple (As supplied by RepRapWporld) is capable of going very hot but 290 as std is easy as well.

The Volcano is a modification to the E3D V6 by the way

I was thinking of higher than 200mm/s (this on a 200 to 50 micron layer height and with a 0.4mm nozzle)

This one also seems nice, but I saw in some videos that the fan mount is sitting quite loosely around the metal cooling fins?
And the length of the heating area is nowhere near as long as for example the pico hot-end.

If you trust RichRap's opinion, the long melt zone is a BAD thing:
