I've been testing blades for another company for awhile now too, http://bladecp.corocks.com. They are going more for the strategy your suggesting but in a symmetrical blade. They are also just a small group of engineers. They are taking forever though in getting their blades out, I started testing them towards the end of December. They are currently making the final products, but will want to do more testing on them before they sell them.

I absolutely loved their final design, the material was SLA since it was a prototype, the final material is pretty light, stronger than balsa, but it absorbs a lot of energy, so I think it will be a good inbetween the plasti-blade and crappy woodies. I'm really looking forward to getting their blades, whenever that happens. They promised us testers some of the first batch.
