best US rider training.. damo , heineken , menk all riding tris

Not so sure about that... Damo generally rides a quad and it seems to work quite well for him. He was looking to test his tri in light Miami winds, but it didn't happen as conditions didn't materialize. Thus far, outside of rough water and windy conditions, quads seem to still be better up wind, but difficult to ride off the breeze. Adam is also still riding a quad and is doing very well upwind. I think that the quad guys are now tuning in for down wind. As the worlds may be a bit light, I'm sure quads will still be in the mix. Only time will tell.

thanks ! I just wanted to add more confusion in riders mind ....

I prefer 4x 34cm model canefire of vectorfins maui.
front 2% decline.
All directions works great on my aguera cr59..
