What type of anchors are you going to use?
For my taller towers, I use 2 screw in anchors for each leg,
the first at 60 ft out holds the guys at 30 and 60 ft.
The second at ~90 ft out holds the upper guy / guys.
I use 1/4 inch guys for the top set on 90 and 130 ft towers
and 3/16 inch guys for the lower sets with 30 ft spacing.
With wider spacing, it would be wise to use 1/4 inch
guys at all levels.
If you ever want to use a long mast and stacked rotary
antennas (a tribander and 2L40 is a powerful combination),
then place the top set of guys as close to the top as possible.
The Rohn drawings ASSUME a microwave dish on the top
section...not exactly what you want to use for an amateur
antenna plan!
BTW, if you put your tribander at 90-100 ft, it would be good
to add another around 40 ft for high angle coverage.
