Sounds good, Phil. If you care to start from scratch, an even better 
solution is to buy two colors of stranded THHN at the big box store, cut 
equal long lengths of both cables, tie one end to something like a vise 
attached to a bench, the other to a drill, with the cables stretched out 
flat, and run the drill slowly until you've passed the degree of twist 
that you want (more is better). Then set the drill down for a day or so 
to let the cable "remember" its twist. When the cable is removed from 
the drill, it will untwist a bit, and the twisting will not be uniform 
from one end to the other, but it's good enough.
