My Tiemco substitution chart lists the TMC8089 as a Sprout, Forged, Wide Gape, Fine Wire, Bronze, Ball Eye (S), Sizes #2, 6, 10. The Mustad equivalent is listed as #33602 which is a Sprout, Ringed Eye (S), Gold Plated, Sizes #5/0 to 16.

The Mustad 3366 is a Sprout, Ringed Eye (S), Nickl., Brz., Gold, Blued, Sizes #8/0 -2,4, 6, 8, 10, 12, 14 and Tiemco has no equivalent for it. Pattern application is wet flies versus Bass Bugs for the Tiemco 8089.

Hope this helps,
