Paradox Evolution 4800CI roll-top with V21 Talon and frame extensions in place. The 4800 was HUGE; 8 days out and i only filled it about 2/3 of the way. Also, plenty of functionality to carry tent pole, axe, wyoming saw, fly rod, cook kit, etc. on the outside. It would be nice to see an axe loop/sleeve of some sort that could be added to the under-side of the of the Talon...like the Frost River Pack/bushcraft-style.
