OK ... This will be GUESS!!  I didn't go that route before but I will say that map is deceptive, especially if you're used to BWCA maps.  The lakes are relatively small, the distances shorter.  My trip notes said it was about a 3 mile paddle from the put-in to Badger Campsite.  Using that as a guide, my guess is that you would have about nine miles of paddling and one mile of portaging (easy portaging).  My guess is you could do it in 4 hours, 5 if you took it slow.  Add whatever fishing time you'll do.

Speaking of fishing, it is extremely regulated!  Be sure you know what is going on.  When I was there, Crooked was under normal Michigan regs, but not the rest of the lakes.  Some regs were: No bass could be kept; no barbed hooks; no live bait, and no SCENTED baits.  If you fish I strongly recommend stopping at Sylvania Outfitters to buy your license, buy a couple lure, and chat with the owner there.  He is very nice and extremely helpful in understanding those regs.

Oh, campsites ... Group size is limited to 5, but two groups can travel together.  Campsites are assigned.  However, some campsites have more than one unit, that is more than one group can camp/be assigned there.  Think of a "campsite" as a mini-campground with one, two, or three sites.  The Badger site we were in had two units seperated by perhaps 75 yards.  Each had tent sites and firepit.
