At least on Shiva.

I did Beetle arrowheads until lvl 31, then switched to these, and I'm 36.something now. I'd keep going, but my inventory is full of arrowheads :) (and so is the inventory of my mule)

Beetle arrowheads sell for 1800-2000 a stack (~13K/stack of beetle jaws)
Fang arrowheads sell for 700-900 a stack (~10K/stack of tiger fangs)

Strangely enough, Fang arrows sell for more than Beetle arrows, even though the ingrediants cost half as much, so if you have good woodworking skill, you may be able to help reduce the profit loss by just making them into arrows.

I would highly recommend farming the fangs if you have a high enough level char, the drop rate isn't that bad if you have THF subbed, especially compared to farming beetle jaws.

Ok, I'm lvling on these since beetle capped at 33. I'm at 35 now and these have still yet to cap. Although I do not get any failures at all, so I am guessing it will cap soon.

Price is for Midgardsormr. People are either farming their own supplie or desperately trying to get rid of these, cos:

1 wind crystals 100 - 120 each. 1200 - 1400 a stack
1 bone chips 110 - 140 each. 1300 - 1800 a stack.
1 black tiger fangs - 700 each 9000 a stack but 700 singles.
---------------------------------------------------------------------------------------
total: 100+110+700 = 910 x 2 = 1820 (stack of 12)at min. price. Sells for 1300-1400 for stack. ; ;
