Includes Henry's Sinket and Aquel. Henry's Sinket: Flies treated with Henry's Sinket quickly break surface tension and rapidly drop in the water column to where the fish are. It helps nymphs get deep, where they roll along the bottom as naturally dislodged nymphs would. It's especially effective on streamers, getting flies down on the first cast rather than waiting until the materials become saturated. Henry's Sinket is completely biodegradable. Aquel: This premium gel floatant is the world's best fly floatant. Aquel is long lasting, silicon based and won't melt when it's hot or harden when it's cold. Furthermore, it masks human odor and won't leave any slick on even the calmest water. (Pronounced "ahh kwel").
