Had my Katana for a couple of hundreds jumps...was coming from a Sabre2-120, which i loved, but it was very hard to hit the "sweet-spot" coming out of my 270 because of its natural recovery-arc. Furthermore the riser pressure of the Sabre is pretty hard doing 270-turns.
Jumped a Katana 120 for a while getting used to the canopy - which is completely different from the Sabre: Much lighter riser pressure, more responsive on harness (doing all of my turn on harness now), easy to keep in a dive when getting out of a turn to high an still getting the gate. Now I jump a KA107 and I am still in love...
Only con is the openings....they are soft..thats for sure....but often off heading (everything between 0 to 360 degrees - if 360 degrees of heading opening actually can be called of heading :-)
