"Do I understand that you imply the 300-series wing that was load tested is the same as the 200's?"
 
The 235 and 320/360 wings are structurally VERY different.
I am building a 360 and a friend of mine is building a 235, so I have seen both wings in disassembeled state.
The spar caps on the 235 are only about 2/3 as thick as the 320/360, which translates to a lot less carbonfiber.
 
Since anything we build in this country has to be thoroughly tried, tested and documented, both of us needed factory verification of our data for the wing load test.
The factory (Ross) gave us the following numbers:
 
L-235, max. GW 1400 lbs. This figure was never and will never be raised.
L-320/360 max. take off weight 1790 lbs., max. landing weight 1685 lbs. The take off weight was raised from the original 1685 lbs. to 1790 lbs. and this is the absolute max. weight at which the plane can be flown safely ( I asked for 1800 lbs.).
