Mark, I'm sure you've moved on from from this thread, but I just found it as I was googling the Synergy Deca. Your story gave me wonderful memories of my time in the world of kites. I was a competitive flier (dual lines), kite store owner, & a kite collector.
I recently pulled out my kite bags & spent a whole day putting together the dozens of dual line, quad line, & custom single line kites from some of the famous kite makers of the 1980's, 90's, & early 2000's. (Those were the glory days!!)
I still have 3 Synergy Deca 31's, 2 no wind Deca's, several Deca 1's & 3 or 4 Minergy 333's.
i should probably start thinking about new homes for all these classic kites.
