I am potentially moving to utah to work in wilderness therapy. I will be backpacking for 8 days on a regular basis in the desert and mountains.

I am looking at 2 packs. A 2 year old Kelty Red Cloud 5600 for $60 (used) and a new Kelty Phantom (from an outdoors shop that went out of business) for $100. I have not seen either pack. The phantom appears to be an older model, but quite high end. It's made of Spectra I believe. I have not seen either of these packs yet.

Does anyone have any experience with either of these packs? Any suggestions?

Thanks in advance
