I am fairly sure I have heard Darren Bundock say something along the lines of
"The Tiger has a pear shaped mast which means we are able to play the mainsheet a little more down wind"

The capricorn masts are very strong, but not as strong as the Tiger: Definitely make sure mast rotation is out to 90 degrees! Don't "dump" the mainsheet under any conditions - The AHPC tuning conditions suggest a centered traveler in most situations (except very light air).
