For those still wondering about fit, this is me in a tagged 30 ST-100x (5'9", 160lbs, 32" true waist). They were tight like a virgin in the knees/calves to begin with but they've stretched out to be comfortably tight now. 
For those wondering about progress of the 100x Kaihara denim, here's a cross-post from SuFu.
Flipped them inside out and found the indigo was bleeding through in the combs. 
After a warm handwash in the shower and drying under the sun. Not much contrast, the Kaihara denim is hard to fade.
