I just bought the Metcalf over the winter. I have done several days this past spring on turkey backpack hunts and I love the pack. I hunted with it during the day after I packed in and it compressed down just fine. I have been thinking of getting the pintler for a dedicated day bag down the road. However, if you have an idea of going out west and doing a backpack hunt you may want to just start out with the metcalf. I think its only 50 bucks or so more than the pintler. then get the pintler in the bag only option down the road, Just a thought.
Full disclosure, the reason I would like to eventually get a pintler is simply for ease of access in a day pack. I love my Metcalf but access into the main bag can be a bit annoying if you are getting in and out alot like you do with a day pack. I have the Mystery ranch Coulee 40 as an EDC bag to and from the station and I really like the tri-zip design like the Pintler has.
