i am modifing a brinkmann nexstar 2c to receive waynes badboy 400 full sandwich. how much heatsinking will this need, as currently there is no way to use the aluminum barrel as on the minimags. there will be plenty of room in the head for some kind of heatsink. i plan on using thermal paste (not epoxy) to help transfer the heat to the heatsink. can i just fabricate some kind of a aluminum slug and attach it to the area around the emitter? i think it will have to be on the thin side as to allow the optics to fit close to the luxeon
