wire question

Hi all,

I'm looking at some wire and am wondering if I should get unshielded
for the steppers (16 condutor) and shielded home/limit/low votage and
then unshielded for the 110VAC for the routers.

I'm wondering what the best combination might be.

I can get 30 conductor shielded and put the steppers and low voltage
in one shielded and run 110VAC shielded.

or ..... starting to loose if I keep playing with the
combinations....

any advice ?

Dave
