Cold weather, or the addition of a live hyd pump / loader would be probably 
the only reason I would use the thinner oil.  Even if you go with the NAA 
piston and oring.. you still aren't doing much for large clearances in the 
pump.

Also.. pump intake is submerged in oil... no problems with oil flow unless 
you are out of gear oil...
