It's probably just me, but I never got that excited about lights that focus.
Whenever I used a stock minimag I never tended to change the focus. I would always switch it to the same level, sort of midway between spot and flood, and leave it at that. Maybe that would change if someone could fix beam pattern issues. . . but I tend to see focusability as more of a marketing thing.
I don't currently have an adjustable focus light - the minimag has the floody Nite Ize drop-in, and that's enough flood for me. When I want flood, I don't really need anything brighter, because I tend to see flood as an indoors option, and don't seen the need to sacrifice runtime.
When I want throw I use a Streamlight ProPolymer 4AA Luxeon. I'm not saying this is the best light on the planet, and I don't have expensive lights by CPF stadards, but it's a useful yardstick here. If you can come up with an inexpensive light that trashes the PP Lux, you are in business.
