Sorry Catfan I need to clarify. What I listed above were the sails used in each of those events and they weren't necessarily the sailmakers themselves using those sails. Although in most cases they were. So for the Qld event Steve Brewin used his own sail to win. Brad Collett used a small head Asby for second and Andrew Landenberger used his own sail. I'll do a more detailed report on the event when I get a bit of time.
Glenn didn't sail at the event but Brad is a great sailor being a former Australian Title winner and 10th in the recent Worlds.
I can't comment about how Glenn has constructed his big head sail as I've not seen it. AUS made comments above about it.
I'll also give my thoughts on the trend to big head sails soon as I've now done 9 races with a couple of prototypes and sailed against one other.

Cheers
