I really don't see anything different about this plant within the wide variation I've seen with everyone else's to suggest this is a different clone.
The only one I've seen that really seemed to have a really different growth habit from normal, was Fbrem's plant that had a whole bunch of growths all clumped up together instead of spreading long stolons.
I mostly agree with Rick from TN...
If you are looking for an unrelated clones for breeding, you need to get them from someone who knows the history/origin of the plant and will be honest about it.
Can anyone here give us some history about the Windy Hill clone?
