I was building up the mental justification to spend $272 on a WASI powerball when I came across a similar item from Suncor for $135. The WASI 8 mm model claims a 40 KiloNewtom breaking load which I believe is 9000# (1 kN = 225#) The Suncor claims 15,000# breaking load for their 3/8-1/2" model (their 5/16 model fits my chain but not my anchor, so this is slightly bigger than the equivalent WASI)
Granted, the Suncor doesn't have as much swivel freedom, but I wonder if the WASI is truly better.
Sadly (and unusually) WEST seemed to have the best price on ths particular item that I found after a quick check around.
