Those look fantastic. The size charts seem to be different on the same page. The one on the left you scroll down to is a universal 81cm inseam on all sizes, but the link on the right has different inseams depending on the waist size.

Looking at picking up a pair of 50s and was wondering if someone can confirm they are quite stretchy. Pretty sure Tag 34 is for me, but I would need it to stretch to 34.5-35 in the waist.

I think they are all the same. As a comparison, I have the OA02 in a 35, and SC Okis in a 33. The SC is roomier, but not by a ton. I would feel ok going to a 36 in the OA for a little roomier fit.
