I use Slipstream from Crusader Weaponry.
I had used all of the various lubes and never found much difference between most of them.
Gave Slipstream a try... and all I can say is... damn.
CLP, Militec almost seem like glue in comparison.
I loan my bottles out to friends, and all that have used it are buyers now.
Not cheap, but there is nothing like it that I have found.
