Single Strand v. 7 Strand wire

[IRISH56]

What's the main difference between single and 7 strand wire, besides the obvious thank you ??

I know the vast majority of guys use the 7 strand for their wire divers etc. but I'm curious as to why. I'm looking at rigging up a wire diver rig and I see the single strand wire available and a little less $$$$. Money is not the driving force for me but it got me wondering what the difference would be fishing wise. Thanks.

Dan, I ran the single for one season. the biggest difference was the kinks. the single was a bit less forgiving. the 7 strand was a bit more. Other than that I saw no difference
