Rigging grease recommendations for long-term-rigged gliders

So, I have been using white lithium grease for decades for all my glider fittings. This has worked out fine, no problems ever, all my fittings have stayed nice, with no damage of any kind.

However, now that I have an 18 meter motorglider and am retired and blessed with time to go soar, my rigging habits have changed. I now typically keep my glider rigged for weeks at a time when flying at soaring safari or contest sites. When based at my home 'drome off season, I have a hangar so I am typically rigged for months at a time off season.

A person knowledgeable about such things recently told me that white lithium grease for the main high stress attach points (wing pins and lift pins) is not good, it dries out and/or cannot stand up to or stay in place due to the high stresses on those components, and the result is scoring. This makes sense to me, and I am thinking about changing to a better grease for long-term rigging. He suggested molybdenum disulfide grease.

I would like to invite comments on this. Are there other options for grease for long-term rigged gliders? What are the best sources (USA) for such greases?

Thanks in advance,

Super Lube comes in an EP version, about twice the resistance to extreme pressures than their normal version:

You could use molyD on the lift and drag pins as they aren't brass, and the main pins never wear (except through ham fisted assembly). But that seems fiddly. I've never seen a glider with more than a few hundred hours that didn't have some fretting on the pins, so it may be inevitable.
