The classic has won many, many regattas. Kathy Kulkoski won the Open Nationals on a flexible flyer. That thing racked like nothing you have ever seen.., and she flat flew.
Don't know why the Ouch! on the line. Before I discovered SALSA, I was using Warpspeed (4 times more per foot).
The lower block is a bit up there, but I find it worthwhile. Many just stay with the stock block, but it makes it difficult to uncleat in heavy air.
