Yeah like this guy said, ZMI is around 40k-50k per hour exp. It's the best way to get up RC quickly although I done 80-97 on natures. Goodluck on getting 91.
zmi is easy but if you want to do it the fastest way its kinda annoying, you have to fill up all spaces in your bank so you can just do deposit all runes and stuff. so your pouches / bank runes get stay in your inventory and all the runes it creates are banked.
