You COULD farm at 16...
With SOS bow and all...
OR you could get to about 42 and...
a) Get the New 6th D Bow MmMMmm
b) if you have a 9 gap You can still get Strong Bow Spirit
c) You have an option to job (and Decently)
d) If you sit out side of any of Hotans Gates You can Do the Ultra Blood Death Flower Quests As well as get one SP per kill on a 9 gap
e) You will be able to have a respectable guild because your above 42
f) A good guild Means possible power lvling (seeing as your pure str you could get to alot of high lvl places not being 1 hitted at least)
And g) Theres Not THAT much of a dif (in price) between a Decent 16 SOS Farming bow and a 42 Stock.. My friend picked up a 42 SOS Good stats or 16 mill....
Hope I helped
