I have a Mystery Ranch Pintler, great size for day pack or an overnighter. I bought it for it being able to carry meat out and its slim for bowhunting. I do find it a little heavy 5.4 pounds but not heavy enough to sell it and buy a cheaper one. It replaced my Sitka Flash 20...no comparison.
Mystery Ranch Sawtooth, thing is a tank. Perfect for a few days worth of gear with enough space for a quartered WT. Also works as a day pack without being too heavy, highly recommend it.
