In 1975, before heading to Casa Grande for the winter, I purchased a SST piggyback container. It was beautiful compared to my military surplus equipment. Unfortunately, my Paracommander would not fit in the small container. I bought two 26' Navy Conical reserves for $25 each, that fit easily into the containers. I used a diaper deployment and rigged the back four lines to release on rings(Four line release). To steer the canopies, I used opposite front risers to steer and used the rear risers to flare.
Standups were not a problem, when I wasn't backing up too fast. The turns were a little slow. I crossed a highway and a power line at Casa Grande, before doing a hook turn. It would have been impressive, if I hadn't grabbed the wrong front riser, turned downwind with no time left to correct.
I jumped these canopies at the big Turkey meet in Z-Hills in 1976. The organizers reported the number of reserve rides taken during the meet. I was not the only jumper jumping a reserve as main, so their report was probably inaccurate.
I finally bought a Strato Star, while in Z-Hills and didn't have to walk out of the swamps as often.
Those were fun times. Paul Juel
