Got my order in for a 3500, weapon carrier, and hipbelt pouch. Couldn't pass this up. Will have a 2015 3500 in foliage with carrier, beavertail, and hip belt pouch up on the classifieds section soon. Love Fusion/Cipher.
I would get the 3500 since it is easy to compress for day hunts but gives you the option for a 5 day hunt. I have both the 2000 and 3500 but I am selling the 2000 since the 3500 is more versatile. The only thing I will miss is the water bladder holder on the 2000 but I believe all the 2017 bags have water bladder holders.
