Zee,

Contact Jay or Pease at http://glasersails.com and they will tell you about their latest thoughts on the a-class sail. Right now I believe the one Lars Guck uses is probably the fastest cut. They will though do some customization for your weight, height, boat and mast. I do not know whether you are looking for new or used, but listed yesterday on usaca.info are 2 A2's ready to rock.
