Vertex 10W all the way! Nothing wrong with the Coyote at all, but the two side by side, the Vertex is on the next level.
Granted, I have not driven the Vertex 10, so my opinion is theoretical, but I have the Vertex 6, and I own a Acsent 18 Apex, so I am basing my thoughts on that. The 3 Redcats all apear to be the same design, but different scales
