I don't think the weight difference is great, if any. The mod was to the carry through on the spar. I have the figures for a 430 SK (short wings) and a 450 UL (long wings) the empty weight of the UL is 3 kgs more than the SK which isn't bad if you consider the wings are a metre longer.
So, for me the problem with the SK and the UL 430 is the lack of payload if you want to stay legal. They fly fine heavy, in fact they fly better as they sit in the air nicer.
Good points about the work that has been done, as I mentioned on the Yahoo Jab.
