McGizmo's tethers are the best there is if you want something cool and from within the community.
dude, I have one of those, and they are very cool. But, they are big I see then for serious use. I had a guy make me a mil spec version, so I won't drop a camera out of a helicopter.
I think you could search lanyards as there a few people that will make you what you want. However, the McGiz lanyards are wonderful otherwise, with one caveat, an M6LT will hit the ground as it is heavy.
If you have many lights it is fun to make your own lanyards I have an entire desk dedicated to that and flashlight service, like a small business, almost.
Oh and don't forget a bead, NBP, you know I had to say that! Sell me your five flute, sell me your bead!
