I looked at that chart and it seemed that what used to be the old Wintec 500 is now the Wintec 250.
However there also used to be an old (15 years ago or so) model called the 250 which didn't have the interchangeable gullet system. If you're talking about the new ones, I'd imagine the cut is different, as well as the knee pads. I like the look of the new ones, the seat looks more balanced, and there looks to be a larger panel surface area, however many people had the old model and I wasn't a fan, but it was reasonably popular.
