I believe that the reason for the differences in curves listed on Mission's website and in the catalog, is due to new curves being added for 2006. I don't believe that Mission has updated their website yet. As for your question about buying a L2 verses a Synthesis. The int. L2 uses a Jr/Int. blade, I've found that they are about the same size as a tapered Easton blade. It also depends on what curve you are getting, because the Hatcher is a shorted blade. I would say that it comes down to PP.
