LOL... the PetsFang works well, you just have to align it so it just clears the work so it mostly doesn't blow on the nozzle. Also, a hotend with a silicone sock that covers most of the nozzle really is a necessity, not an option; but I think that's true with any 'fang.
When I say close, I'm talking like clearing the work by 1mm or so. The drawback to that is that if you have a print-fail that curls up, it'll do this.

OTOH, that kind of fail is much less frequent with the 'fang because it will freeze the extrusion in midair... so then the choice becomes a matter of tuning.
I'm rocking the stock parts cooler right now on the Diggro; I never got around to putting the 'fang back on after I figured out that the SS nozzle was what was fucking with my head.
I liked that BMG-Mosquito clone I linked to a few pages back; I prefer the BMG extruder to the Titan in general, especially since I started using the CR-6, which stock extruder is similar geometry only pinion-idler instead of dual-pinion drive.
Definitely don't care for the Hemera clone; if you're going to clone a thing and make it weigh a ton... least you can do is get rid of the fucking modded stepper motor.

Non-standard stepper motor is a big non-starter for me.

My best educated guess would be that the first thing to figure out is what you're looking to get out of DD... more precision/cleaner prints vs higher flow/faster prints vs working with more demanding filaments...?
