RE: evo 75 wood or technora
There has been a server upgrade and I think your question got lost somewhere.
Both Technora and Wood use the so called Dur-x construction which is the strongest availiable. Both have heel bumpers, special reinfocements etc. I would say the main differnce is weight and price. A good thing about Technora is that its easier to fix up nicely if you get a damage to the area where the wood is on a wood board. Some people claim a slighlty nicer flex in the wood version too, but the difference is not huge wrt this.
