As far as what is a "good" rotor, I think you have to consider what you are
turning. I am currently using 4 Tail Twisters, 1 Ham V (or IV or whatever)
and 1 M2 2800. Just the other day I clocked winds of 68mph (40 ft up on
one of the towers); and I have not had a problem with any rotor at winds in
excess of 70.
The largest antenna I have is a Force 12 620/340N. It has a boom of 47 ft
and wind load of 18 sq ft. Obviously I am not trying to turn it with the
Ham V, as I believe the M2 2800 is much better suited. I reserve the Ham V
to turning a 9 ele 6 mtr beam with a wind load of 4.8 sq ft.
For large antennas, I think the M2 is just fine; but I am sure the rotors
mentioned by others on the reflector are just as good. Just make sure you
are not trying to turn something the rotor is not capable of turning. By
the way, I believe the boom length makes a big difference. I think Hy
Gain rates their rotors by both boom length and sq ft. I'll let someone
with more of an engineering background address that issue though.
