I think there was an old super rare thanaz one as well back in the day. Diesel raws are kind of a joke, I mean the turbo denim is fun but very poor quality and I have never seen any decent fades from the other ones listed above, but they look ok just clean/raw as is.
Thavar and Shioner are not carrot fit though, FYI. Sleenker fits very tight in the legs so you would likely not like them. Darron is a tapered fit with a looser leg opening, but doesn't fit as tight in upper half as tepphar. I encourage you to just try on a lot of stuff while youre there and see what fits your style and your body type the best!
I was going to recommend the starch thing too. The only downside to very infrequent washing is the crotch will blow out easier, bacteria, dirt, whatever gets in there and causes it to tear. So it's a trade off really, I think most of the members here have a lot of jeans to wear so for them this is not a big issue, but if you have only 2 and are wearing them a lot it becomes one.
Awesome man, I am about four months into my petit standards, are you wearing them quite a bit or sporadically? I spilled green food coloring on mine (st patties drunkeness) and had to soak them early which sucks. :(
