Well since you can't wear multiple staves at a time, you will still need the basic runes (for example, for Varrock teleport, you will at least need either the air runes, OR the fire runes) And hey, F2P's can free a lot of spaces up... for example, if you're not gonna fight for a while, why would you fill up you bank with armour? just sell the full rune for 200K, and when you eventually need the armour, just buy a new set. This frees a lot of space, and even provides you with some extra money... That's just my suggestion, works for me:)
