I built the 168 per instructions to prove that the plane would fly as designed. And despite my reputation I flew it like any normal person would that just built a 1200 dollar airplane. Was so scared the first couple flights, and I thought it was going to work but after a few more it failed. So I guess we will just have to wait and see what SIG says. I still however recommend struts on this aircraft and anyone that is building one to do so. It is an easy application and will save all the hard work everone has put into or is going to put into this plane.
If you need proof of concept, i have a 11 foot cadet senior with a 2 foot cord. And it has no means of connecting the to wing panels together. It has 4 nylon bolts to hold the center section to the fuselage and struts to hold the wing panels on the plane. Much like any full scale Cessna.
