The Slim Guy has the same rise as the Weird Guy. I wear size 32 in both, and I measured the front rise at 10.5" on both cuts.
I don't find that they fit that differently in the upper thigh, but the Weird Guy is a lot tighter around the knees and calves due to its extreme taper.
I've never measured the differences in the thigh and rise, but even if they are the same, the overall fit can be very different. The WG are tighter in the thighs--maybe it's just the lower?--but the biggest difference is up top. WG are pretty much unwearable for me because I can hardly bend without them falling off my ass. I'm guessing others have this problem, because I don't think many are buying slim guys for the massive knees and ankles.
