The neat thing about wire is you get the benefits of a hardshaft yet the flexibilty of cable...within reason. Gentle curves work best.
I can only think that cable under load and thrust wants to coil up so I would think it would put more resistance in the stuffing tube. I ran cable in brass tube witout teflon in most boats for some time and you can hear the cable making lots of noise from pushing on the stuffing tube...one reason grease is needed.
On wire a light lube is all that is needed and I have even used light turbine oil. STP oil treatment is another good option or you can just grease it up ---but not much actually goes on the wire like cable. Oil, wire and teflon is very slick and fast.
Many were running wire inside of 1/8" brass for the stuffing tube and this still works very well. Recently, the teflon has been the best choice...faster, smoother, less noise and you can leave enough exposed teflon at the strut to make adjustments.
I mentioned above that big rigs will be testing .72...I was wrong, it is .78 wire. This should be able to hold up to the same power levels we have seen the German guys run at over 120 mph with 32 cells. They were using 2.5 this past SAW but the year before they ran 2mm wire. They ran SS wire.
Connectors are made to fit the major model motors. 4mm,5mm,6mm, 1/4" and all to fit wire in 1/16 or .78 for the monsters.
Otherwise the Octura 5mm and 1/8" Flex hexes work well with the 1/16" wire.
I have only lost one prop and it was attached to Flex Cable. Cable can rust from the inside out...may never see it on the wrapped outer core but cable has a wire inside and when it goes you are done.
