I started with a bunch of Javelina sticks a friend gave me when I first got into casting. I've about run out, though I do have one or two sticks left and I love the smell.

In the search for a new replacement I've tried Lyman and RCBS lubes and had good luck with both of them. I've been using mostly the RCBS green because that's what the store I buy that kind of stuff from stocks and it's a buck a stick cheaper than Lyman.
