What skill should I get 99?

I have 99 fletching (in Runescape) and I want another 99 to get my cape trimmed. My closest other skills to 99 are 79 firemaking and 89 woodcutting. Should I do one of those skills or does anyone know a skill that can be a fast 99. Preferably a profitable one but it doesn't have to be able to make profit.
