The pic is my 6A with a two inch extension on the bottom of the panel. The stick just clears the panel and throttle, since my thumb won't be on top of the stick. The passenger stick clears the panel with thumb on top.
With the type of stick I've got, the face with trim buttons are angled towards me. I just sat in the cockpit and oriented it for the most natural angle/feel.
This is also my second stick, which required additional cutting off of the original, because of it's longer base length. At least if you cut too short, there are always sticks that can make up some difference.....up to a point.
As to control and feel, I'd say that my stick length is perfection. Others think the same.
