Personally, I like a little forward lean anyway so it didnt bother me. I loved the cartels. Very comfortable, solid construction, good straps, the reflex is nice.
can't really comment on your set up, I am huge compared to you and ride a lot different type of boards. THat being said, I have heard good things about the Rossi and I am sure you will love the Cartels. I believe the Retox is a mid stiff freestyle board. The Cartels will pair up nicely.
