We've never had issues with signalling buddies in a cave. I'm of the thinking that, if you're have a problems signalling your buddy (assuming you're following proper buddy protocol) with the spots on the high powered Light Monkey or Hollis LEDS, you don't need a new light…you need a new buddy. Obviously they're not situationally aware.
The form factor of an LED with it's smaller heads is much nicer. And if you're thinking of helmet mounting the light, the Light Monkey and Hollis are easy to do.
