I have one and like it a lot. I can get a large C&F box (20 row) in the main compartment and a smaller box in the front compartment. This leaves room for leaders etc in a zippered pouch in the main compartment. There are plenty of tie outs to attach various tools (nippers, hemos, etc)
I ditched the waist strap and just use the neck lanyard – which are fine with me. The pack isn’t big enough to get very heavy unless you dangle a bunch of accessories off of it.
