I recently purchased a V10R titanium and, despite an eagerness to buy a kuku titanium clip, I've found the stock clip to be surprisingly useful.
Specifically, I've just found an interesting "feature" I haven't heard anyone mention. After polishing all the black paint off the clip, I carried it for a day before I realized I could flip the clip upside down, and use it to clip the light to the bill of my ball cap. Hands free operation!

If you make sure the bill of the cap gets all the way to the top of the clip, it's a solid fit and doesn't move around when you move your head.
