#35 Chain

Every one I've tried so far pretty much stretches right away and fairly easy (I'd say mainly due to how small it is) but I'm using it for original application therefore I don't want to go to a bigger size.
As already mentioned in that other thread- RLV Xtreme.
do they make a o-ring chain in #35? I have looked but no luck yet other then some industrial lookin stuff that would probably stretch like cheap stuff.
