What is the fastest way to 99 Thieving in Runescape, besides Pyramid Plunder?

Can anyone tell me what is the fastest out of these, as in most xp per hour (if I do them all at the same speed) Thieve's Guild chests, Thieve's Guild coshing trainer/volunteers, or Bandits in the desert? I am almost 77 Thieving right now, and I want 99 as fast as possible, but I absolutely hate Pyramid Plunder and I am unable to steal from Monkey Knife Fighters. Also, I could take the time to figure it all out on my own but last time I tried to do something like this I got hopelessly confused. Thanks ahead of time!
