If its a 460 NoLimitz made Ezzy mast, I would be a big careful getting other sails than Ezzy to it. I was about to recommend the Hot Speed Demon no cam sail (which is at last fast enough to win the italian slalom championships in competetion with all well known cam sails...) but I'm a bit unsure about the mast fit.
I believe the NL made Ezzys are a bit softer in the mid part. Then they should maybe match up with some of the Gaastra sails. But definitely try the sail on your mast before buying.
