Nice, pretty sure I will reach that point eventually.
Annoying.The only problem is they usually don't fit too well, to say the thread spec is followed loosely would be a massive understatement. They are also usually painted as well.
No, but I still like the idea of making full use of such a nice piece of metal.I'm sure it adds a little bit though, not a direct replacement for mass attached directly to the diode though!
@ TJ and Flaminpyro:
The dust cap problem can be solved easily...
Instead of cutting out the "nub" from the commonly used GITD silicone tail caps, leave it and cut off the "outside" of the tail cap.
This will leave the nub exposed and the top (textured part) of the tail cap.
The aperture should be ~5mm dia. to allow the nub to fit inside. Instead of the dust cap fitting over the focus ring, it fits inside.
Here is a picture of how I implemented it in some of my builds:
