For Silicone materials Maximus is my favorite, Anal lube from Cal Exotics is good as well. Doc's Anal Lube sounds pretty good but it has Silicone in it so be careful with Silicone toys. Probe Thick and Rich is nice but it dries out to fast for me.
For materials that are compatible with Silicone lubes, Better Sex Essentials is my lube of choice.
