Fastest way to 99 fletch?

[iJonny]

I heard headless arrows and adamant arrowheads is good?

 

[Sham Wow Wow]

I'd just do maple long (U)s all the way and then high alch them.

Making adamant arrows is fast, but expensive as shit.

I suggest making Mithril Bolts, it's relatively cheap and you can make some mad xp / hr.

What you said is even faster with dragon arrows, but that will cost soooo much...
