It's hard to beat these for the price...http://gossamergear.com/shelters/shelter-accessories/tarp-pole-set.html
I bought a set for my Golite Shangri La, and with a few inches of trimming on them, they're perfect, and really light yet stiff. They break down short enough to fit in a frame bag also. There are two options for pole lengths. 45" with a 32", or a 42" with a 24"... Also added some nice wide and blunt Trekking pole ends to the ground end, which prevents them from digging in to the dirt throughout the night.
