The Eberlestock X2 pack has side pockets for scope and tripod so you don't have to put them in the main compartment with everything else.
This is what I use. Its not as high end as the Kifaru or MR's but it works well for its intended purpose. The main pouch is just a big bag that you could easily get a boned out mule deer into.
The frame rides on my hips well, and I've had no problem carrying it all day. In a pinch, I can shoot my bow while wearing it.
