Recommend either a PST-61D or the Orion 2800 with the Green Heron
Controller. Either way you won't have trouble turning the antennas even in
high wind. The PST-2051 may be a little light.
With the PST-61D I followed Array Solutions advice and replaced the mast
clamp bolts with hardened bolts and really cranked down on them with a 2"
mast. There has been no slippage whatsoever. 

No experience with the Alpha-Spid.

By the way my PST-61D is turning a SteppIR MonstIR at 85'.  It used to turn
a C31XR, Warc-7, 6-el 6M and MAG240N on a 32' mast without any problems too.

It appears that my Hy-Gain T2X Tailtwister is not going to be large enough
for long term survival of my 4 element 20-6M Stepp-IR stacked with a 2
element 40m Cushcraft 402-CD 12 ft above it.  After only 6 months of being
in the air over a relatively mild winter and only one day of 50 MPH winds a
couple of weeks ago, the T2X rotor is trashed.  Fortunately, I have a second
T2X that I put in place to keep me on the air until I can upgrade the rotor.
I am used to swapping out and rebuilding rotors every couple of years, but
every 6 months or less is not acceptable.

I have settled on either the Prosistel PST-61 or the smaller PST-2051.  I am
sure the PST-61 will do the job very nicely, but I am suffering from sticker
shock and was wondering if the PST-2051 would do the job?  Comparing
specifications between the T2X and the PST-2051, it would appear the
PST-2051 is slightly heavier than the T2X, but since manufacturer's
specifications are very subjective, is this really the case?  Would I have
enough safety margin with the PST-2051, considering the overall design of
the rotor is completely different than the T2X?

I am prepared to spend what is necessary to purchase a reliable rotor, but
at the same time I don't want to overspend either.  This is probably the
largest antenna array I will ever put up at this location, so upgrading for
future expansion is not really a consideration

l would appreciate some real word experience, as it is often better than
relying on manufacturer's specifications.

Thanks and 73
