This pack suits tiers who want a dedicated tarpon hook with a heavy build and a clean, simple shape. The XS415H BN5X is a straight-eye, wide-gape pattern with a forged bend and extra-strong wire. It’s meant for tarpon fishing and holds up when you lean on a fish. The micro-barb is there to help the point go in without a lot of pressure, then stay put.
In our options, the difference between #01 and #02 is simply scaling the same tarpon-heavy design up or down to match the fly size you’re tying.
