High Peaks Multiday

I am trying to plan a multiday backpacking trip with a friend who has very little hiking experience (we're both college athletes, so we are in pretty good shape). I have a good amount of experience with day trips in the High Peaks but I have never backpacked in them. Does anyone have any suggestions for a 3-5 day trip? I am open to anything - so far I have done research on the Cranberry Lake 50 and a few Great Range variations but I would love to hear about some other options. Thanks!
