Glad to hear you are out flying John. I'm pretty pleased with the current kite V3.1 - the kite you have with a shortened upper spreader. Give that a try when you have time.
The kite has met the original project criteria - a wind efficient mix of ballet and freestyle. It won't change the world but it is a nice fly and does well in my field conditions. I believe the design to be stable and matured at this point as I'm spending more time flying than testing and tweaking these days.
Still have not developed a true indoor/no wind version yet so may play with that. Also plan to scale versions down to 6' and up to 10' as future projects.
May well slip a quad or two in the build mix but first have one more set of kites to build and send out for the testers group...
Flew the Enigma SUL Friday night in low wind. No tail weights.
This is the V3 version of the Enigma but with the longer upper spreader.
The kite will still do either a barrel roll or a backspin depending on input.
Don't change a thing.
