I don't like to own a wardrobe of packs, so I have just 2 - a daypack and an all-season backpack. I love my Circuit, but I bought it about 3 years ago before it came in a small, which I really need. So I took a chance on trying a frameless pack in a size that fits better. I packed it up with my usual gear, and it looks like it's going to work great.
The Exodus is scrunchable to handle a variety of volumes, and it barely weighs a pound! I do all my backpacking in the PNW, year-round, usually above 5,000', so I always need a puffy jacket and a 20 degree bag or quilt, which I like to pack with lots of fluffing room at the bottom of the pack, rather than compressing to a down brick. I chose the Exodus to meet all those needs.
So I don't consider it too big, because it easily can be made smaller, the weight is not an issue, and the frameless style seems to work fine.
