AMA soaring columnist Mike Garton addressed this concern for DLG's about a year ago with an XP3 and other side arm launchers. His main concern was for rudder push rods or pull pull cables breaking after the high stress of DLG launches.

Your Chrysalis isn't a DLG, so I'm sure you can use pull pull with much more security. I have a Fred Mallet Epsilon with all spectra pull pull controls (rudder, elev) and it works great. Just be sure the tension is enough, but not too much for the hinges you use.

One good trick I learned from Fred was to wrap the pull pull lines under the servo screw after threading through the servo control arm. The screw locks the cable in place, but you can still loosten for adjustments. 50 lb spectra kite string is a good thread to use. It's slippery and strong.
