"What to buy" for archers~Guide + Questions

I have a:
Clean Zakum Helmet
100%'ed overall
Clean earrings
3 Dex YSS
11 Atk Gloves ( Borrowed, but won't be much of a problem )
2/4 Dex PAC
90 Atk Asianic

Uh, since this is my secondary character I'll spend up to like 50-70mil. Maybe more if I make some mesos.

Should I just save up for a lv80 or lv90 bow?

Let's see.. 90 atk Asianic. I want to say go for at least a 100+ atk arund. I think you'll be able to afford that; it depends on your server. However, if you level fast, and really want a better bow, save up for a Metus.
