I smoke #2015 and #2035 regularly. #2035 is the more unruly of the two. I have good luck keeping them as whole flakes (as you purchased them) and letting them get on the dry side to the touch. There's plenty of moisture for "healthy" tobacco within the flake. When I go to smoke them, I give the flakes a quick, rough rub or two just enough to break the flake into smaller pieces of flake, but I do not get anywhere near fully rubbing them out. I drop about a 1/3 of a bowl into the chamber and tap the bottom of the pipe to settle them (I do that with all tobacco). Then I very lightly push that down with a finger. Again, VERY LIGHTLY. Fill, tap it again, and then hit the top with flame. Tamp. Re-light. Muddler's by thirds is also a great technique, particularly for flakes.
My guess is that many people get flakes too compact in the chamber and don't allow for enough oxygen to get around the tobacco. You can't do that with a flake. There's less surface area and more density than a ribbon tobacco. You need additional airflow to compensate. Not to imply that you need to leave a flake completely loose in the chamber, but comparatively, you do have to leave a lot more open space for it to ignite and continue to burn. Basic fire principles there.
Personally, I'd rather leave more space than going the dryer tobacco route. I've found you get a much more complex, nuanced flavor palette when you begin with a moister tobacco. For instance, and I said this the other day somewhere else on the board, when #2015 is too dry, you lose the chocolate and molasses hints. You get a blunt sweetness and not all those great little flavor spikes. The reason I choose one tobacco over another is usually because of its nuances. I'm forever searching for them, so I definitely don't want to do anything to streamline the flavor.
