I Need Suggestions!

Calling all adventurers: I want to go backpacking this Friday and Saturday before the cliff jumping trip on Sunday (my birthday - and you're all invited!). I did a through-hike in the Superstitions two months ago; I'm considering an overnighter on Flat Iron, but I'd love to hear some suggestions from the locals! I'm actually still pretty new to the area; does anyone know some good 10-20 mile backpacking trails in Arizona?! :D
