Install turbo fins and make sure your seat back adjustment straps are not slipping and that is causing you to be leaning back/aft too much.
It sounds like you are holding on to the carrying handles because you are leaning to far backwards.....yes?
I found that my seat back, plastic "strap slide adjuster" did not fully secure the strap and they would slip, causing me to lean back/aft too far.....I solved the problem by tying a " 1/2 knot slip loop" with the tail end of the strap so it would stop against the slide adjuster. That prevented the strap to no longer slip in the adjuster.
If I wanted to adjust the seat back position, I simply pulled on the tail end of the strap and it would come undone for seat back repositioning....then re-tie the 1/2 slip knot again.
Think of tying a 1/2 bow knot in your shoe lace....that is the knot I am trying to describe,....click on http://www.southee.com/Knots/Knots_Miscellaneous.htm

This simple solution worked for me
