Using three separate insulators, one in each leg of a guyed tower, is about

I agree and I felt very uncomfortable with the tower leg insulators for that
reason. Tower leg insulators seem to be the only type readily available to

I can fabricate a full pivot base.  The base is free to rotate (slightly) in
the x, y and z planes.  I could then mount the leg insulators above the base. 
How does that sound?
