Like many others it seems; i've found it to be a comfortable seating position with the seat backs rested directly against the cross brace, disregarding the hinged seat back brace. However, I am not happy with the seat back just flopping there and not locked firmly in place, as it is when the hinged seat back brace in play.
So, i ordered two new F-638 seat back braces (only about $10 a piece) and fabbed up a couple shortys. I cut about 1-3/8" off the leading edge of the factory brace with a tin snips. This puts the seat backs within about 1/4" of the cross brace. I used some leftover hinge from fuse kit. Now I can have the postion I want, with the seat backs firmly in place. Surely I cant be the first to do this, but just thought i'd share. $20 and an hour of my time...

My seat backs have rested directly against the cross brace since day one without a problem. They do not flop around. Just more time, money and weight that you will never use.
They are easy to install later if a new owner happens to be much shorter than you. Keep your airplane light. Don't install anything that you don't need. You will be rewarded with an amazing airplane.
