I have had 9143 Z-Axis in the Rod Pool for about Two years now and have had good success with the following lines.
The rod seems to have a grain window from 500 grains to about 700 grains.
You if you want the heavy feel go heavier or go light if want more line speed.
I have some of these lines in the Line Pool
The best way for you to know what you want is to try a few lines.
Aaron's covered the ground quite nicely .. only thing I might add (if you're into spending 'big bucks' on a hell of a full dry line would be the 9-10 Carron line. If memory serves, Aaron also carries these.
