Risk or play safe?

Im playing on Yellonde atm, and just before the server check, I landed a 10% and a 60% bow attack on a 3 above hinkel.

So the current stat is:
90 atk
1 dex
5 slots

I have 2 30%s, around 2x 60%s, 2 10%, 5 70% bow atk scrolls left. Just wondering what I should do next.. Should i just play it safe and 60 the rest? hopefully end up with a 98-100 atk bow.. Or should i 30 a few slots?

There aint many scrolled bows in yellonde atm.. especially high lvls ones.. other than 7x100% ones..

What should I do?

I posted this on sw.net too, but i thought there would more experienced bms here so i posted here also. Thanks for the help =)
