Fished a Sharkskin?

I need to replace a #5 line on a rod that I use when I want to heave it out
there as well as fish more normally

I'm considering a SA Sharkskin ... 'one born every minute'

Has anyone here actually fished ( as opposed to cast ) this line enough to
provide feedback on things like

does it pick up dirt badly ( all the little hollows? )

does it cast short well?

does it mend well ?

does it REALLY float as well as advertised? and for all day?

will the line noise drive me nuts ( short journey ) ?
