St.Regis Ponds loop ~VS~ Floodwood Loop

I think I have narrowed it down to one of these two trips this summer. The St. Regis Canoe Outfitters site describes the St. Regis loop as "strenuous" (5-6 days), while they mention the Floodwood Ponds loop can be done in 1-2 days. Seems like these two trips are very different. Can anyone compare/contrast based on experience? I feel like I am looking for a trip that falls in the middle in regards to rigor. Thanks in advance..
