I can't tell you about the 8's...

but my wife and I picked the 10 wing up with all wiring, ap servo, roll trim, 50 watt hid except wing tip and it probably weighed at least 175 lbs. It was all I wanted to lift by myself on the inboard end.
 
wind weight

My wife and I handled our -8's wings enroute to airport and also moving in garage. One wing is very light and easily lifted/moved with two small people. Ours are at the airport; I'll try to get a weight in the next week.
 
Does this wing me me look fat?

I weighed them by standing on my bathroom scale, lifting one up and subtracting.... I got about 110lbs (it's hard to hold perfectly still while standing on the scale and holding the wing)

The wing tip is not installed and there are no electrical items installed.
