Ok, two weeks later....
I have managed to farm a stack of ice kobold furs over about five nights in this time, roughly one to three hours or about four complete clears of kobolds and spiders, top to bottom including 'top dogs' (no basement), per night. It seems as if the drop rates are bursty; I would see three furs in an hour and then nothing for the next two hours. With the average rate I have gotten ice kobold furs, I can now say that I believe that the drop rates of ice kobold are just about on par (maybe just slightly lower) with the economy demands and how much a sane tailor can farm to keep up.
However, when sorc lab is camped, I gave stormwolves another shot and to no avail. I have farmed stormwolves for about half that time that I have spent in sorc lab in the last few weeks and have yet to have a single fur to show for it (aside the one I have gotten from other players in this time). It probably has to do with the fact you cannot 'zerg kill' the stormwolves as much as you can the kobolds, and the drop rates do not reflect this fact.
So, given the risks of hunting in western wastes, the difficulty of stormwolves, and the current drop rate, I do believe that the drop rates of stormwolf fur should be looked at and increased.
