[TowerTalk] Rotor Cable size

[Dan Bookwalter]

Sorry for the extra bandwidth I forgot to include this with my feedline 
question...

I will be turning the PRO57B with a Tailtwister , and am wondering what size 
rotor cable I should use , the run from the shack to the rotor is about 250' , 
Texas Towers has several to choose from , my guess is that I need one of the two 
larger sizes.

they list these two larger ones on their website:

R83, (2-#14, 6-#18)
R84, (2-#12, 6-#16)

thoughts/experiences ?
