Thanks for the info Gene.
With out having the tower, it is pretty difficult to decide exactly how I will
terminate the wire to the tower yet.
I will stay with the #2 solid. Keep it simple. I just want to get all the
ground work done soon. I will leave plenty of slack for connection to the
tower.

be somewhat more flexible.> Is that a good idea, or should I just stay with the
