What is the fastest skill to 99 in RuneScape?

If you ask me that would be fletching, otherwise they are all the same, but cheapest has got to be hunter.

completely wrong fletching can take months construction is easily the fastest skill taking less then a week easy if you have money, and you can also make more money doing magic then hunter (I made 21M for 91-99).

the fastest skills are the most expensive and the cheapest skills are the slowest.

this is kind of true but construction is both cheaper and faster then prayer. While you can make money (not a whole lot) doing theiving; there's even a guide to get it from 1-99 in 94 hours.

hope this helps
