I like the carrot fit of Tepphar. I did try on some 886z in the Diesel store along with Sleenker in the same wash. I decided to go for Sleenker on that occasion but had the Sleenkers not been available I would have gone with Tepphar.
No, my rear doesn't suffer and no there is no big material tension. I have jeans as tight and they have not ripped in the crotch. Anyway, that is just your opinion. Like I said, if I wanted a looser fit I would have gone for Larkee.
