That may be true...I got one of the Bosworth GTX Pros from TW way back when, and it's suede side out, but definitely leather. I never unwrapped it to confirm.
But it's still just the rough side of leather. Maybe they have the smooth side roughed up as well, in case they wanted to re-wrap it.
I love Wikipedia, even if there are questionable submissions and data there. But I think this one's spot-on.
