Don't do that, stick with DoN, it is by far the fastest route and you could be max skill in 8 hours or so. If the appropriate level silk, pelt, ore is not available in bazaar, move on to the next level and then the next level pelt/silk after that.
Exquisite silk/pelts sell for under 15pp, and they are always in abundance worst case is to use those as they are dirt cheap. Or 2nd thought, setup a buyer.
For me it comes down to is spending 2-3 hours getting to the zone and farming 2-3 stacks worth my time when there is another pelt/silk 1 tier up readily available. You have to remember most zones only hold 100-150 mobs, and the drop rate on this stuff is about 10-12%. Then you have to wait on re-spawns after you slaughter the whole zone. Unless the price is just simply outrageous, stick with bazaar for all your tradeskill farming.
If you are only trying to get to 150, do the quest in crescent reach to get skill 54, then find the appropriate level silk/pelt and do the combines suggested about, if you can't find those move onto the next. It doesn't take but about 3-4 stacks of silks/pelts to get to 150 anyways.
