ImageShack.usI approached it from the angle of flight stability and safety. So the jump suit should have the man jump yets on the back, angled not fully down, but tilted a bit towards the back.
The tip of "wings" hold thursters who's main purpose is strafing and providing a coutner-force so the suit doesn't tip fully forward in flight. The intakes are above the shoulders, angled so they could take in air even if jumping. superman-style
Aditional thrusters on the legs are questionable.
