Hi Don,
You left out something REAL important in your posting. What did you do about a
rotator mounting shelf after you got the T2X inside the 25G tower? If you did
any
cutting on the existing shelf, that could be as bad as removing a brace. If you
attached the rotator shelf to the horizontal bracing instead of the tower legs,
that,
too could be a serious weakness. It would be real informative to know how you
mounted the rotator . . .
