Agreed! Insanity, especially with a skirt on a grounded tower. You'll
never know what you have until taking a FIM out to measure. When you
find it is not tracking with theory, fixing it can be expensive. Far
better to drop it to around 210 deg, model it with guys and anything
else planned for it, then build it. IMHO anything over 200 deg should
be very carefully evaluated before stacking steel.
