You are correct that the Steppir puts more torque on the rotor and mast. I
think any of the rotors you mention will work for your 3el. But they should
be controlled by a Green Heron control box with the ramp-up and ramp-down
feature, it makes it very smooth.

I have a US Tower MA-40, a MARB and MAF. I also have a SteppIR 3-element
beam. What rotor do I need?
One knowledgeable person about rotors has suggested thatSteppIR's put a
lot of torque back and forth on rotors. He thinks a HAM-IV will getdestroyed
and a t2x is marginal
for the 3 elSteppIR because of the 16' boom and 36'
long elements even when mounted inside a
tower on a rotor plate.? He wonders
if a t2x can handle the rotation of the MA-40 tower and the SteppIR as well.
He
knows of many people using the MA-40 rotatable tower as I? want to do, but,
they
aren't adding a SteppIR on top. He suggests abigger rotor or?smaller
antenna.
.
I know some people who are using a HAM-IV to rotate a MA-40 tower, but, they
do
have smaller beams. Please let me have your experiences and suggestions.
