Best grease for poly bushings?

[Bigsyke]

The issue is, the supplied grease with Energy suspension will grip the inner casing to the bushing, causing bind. The grease is not "slippery" enough to provide quick movement between the surfaces for daily driving. It is also too thick to remain inside the bushing when the inner casing is pressed into the bushing. Unless you make slots inside the bushing, all the grease usually gets pushed out when you push in the metal casing. Plus this stuff sucks, so aside from white lithium (which dries up), is there a super effective grease such as;

Synthetic brake grease
Synthetic marine grease
Moly grease used for transmissions?

I would assume the marine grease would be water repellant, the synthetic part means it would disclude petrolium, which eats poly bushings, but doesnt moly grease have a better sheer rating?

What are you using?
