I've been playing with the 18500 TnC SF tube and it's a really slick set up on the VIP BBH. The other VIP heads look like they were made for it as well. This may be my favorite beam to date using the X bin through the 3" reflector. You get roughly the output of a trilux but with more throw with a tighter hotspot. I also have an adaptor ring to mate the AA body straight to the VIP heads but it's a little strange this way.
Chris also posted some lantern polycarb caps on his site. I find this type of lantern setup very useful.
