Do aluminum mast sheaves need any lubrication? Which one? Can this be done with running rigging on?

samson warpspeed 3/8" dyneema core diameter?
Does anybody know the dyneema core diameter of the 3/8" warpspeed line? Either warpspeed I or II.
End for end dyneema splicing is best done with the same diameter rope, right?
Thanks!

It's a 30' sloop. There is a 90% jib on the roller furler, so it should be 11' foot length + 30' boat length + some extra. You're probably right. 50 or 55'.
