The big advantage of the T10 was that left to itself it went from up to down. Even if the jumper never touched a riser they would end up ok.
The -1 required you to actually think while you were in the air and get yourself positioned correctly relative to the wind direction. If you didn't touch the toggles and you were in marginal winds you were in for a real surprise when you landed.
