An ill pill question.....

[**DONOTDELETE**]

As soon as Lambda gets my money order,I will be recieving a mini mag modded with an ill pill.I have decided to go with a tailcap switch on this light,and was wondering if there was a way to increase the heat sinking on the mod so I can run lithiums in it.I was thinking some thermal epoxy or something since I wont need to turn the head to switch the light on.So..Lambda or anyone else,what would be the best way to do this?
thanks,
troy
