Know nothing about the boat, but Critical Twist, which often sailed with the PDXs, was happy with used 49er spinnakers. Search on 'spinnakers' in this forum for various strings. The first PDX boats had a bulk buy of North sails from the Portland loft and seemed to be happy with them. My sails are based on that design and I am pleased.
A comment: I regret going to a max luff-length main. I am reminded too much of sailing my OK Dinghy when I tack! This winter my main and jib will get windows for collision avoidance.
