  survival ranking on Scoraig is similar to clive's although our 
windpeeds must be lower.

One big advantage of the AWP is that the furling system is extremely 
simple, unlike the Proven where it relies on springs and highly 
stressed plastic hinges.  The Proven has much more consistent output 
in high winds though, when it works right.  If you need continuous 
kWs.

the AWP is actually designed for low windspeed sites, and the 
production version has some cosmetic changes which made the tail 
hinge more compact.  This has increased the wear on high wind sites, 
which will be a problem for us in years to come.  I can argue with 
awp about things like this but they don't seem to listen.  It's not 
going to be a big deal to fix, when they do wear out.

quality control is an issue, as it is with all small wind 
manufacturers.  I can't predict the winner on that one.
