Testing out the best Loc products

I've experimented with a lot of products to twist my hair with.  Honey, Jamaican Mango & Lime, Murry's Beeswax (cringe), and a couple others.  I still haven't found the best one for my hair.  Alot of the products just sit on top of my hair, then in a few days I get massive build up.  Then I have to wash and the process starts all over again.  So it's time to find something new.
