The SNFC Camo features a tapered base between the leader and the fly. Its camouflage finish is the key difference compared to the SNF Classic of the same length. The “X” number indicates the fly’s thickness, but be sure to also check the diameter of the butt section where it connects to the leader. You can extend the leader with a tip suited to the fly’s size. A tip that’s too long or too thin can make the cast less even: adjust these two parameters together.
