Roger,

I want to understand exactly what you're saying here.

In a strong wind, would you expect there to be more total compression in the
downwind leg with guys attached? I would expect just the opposite...

In low winds, yes the static compression from the guys will add moderate
extra loading, but I would expect the curves to cross at some medium wind
speed. This is for a rigid tapered tower (which doesn't exist), but I'm
betting the results are similar in most reasonable real life scenarios.

Rigid tapered towers certainly do exist
