The Pro Leech by X Zone is an ideal bait for Smallmouth Bass, Largemouth Bass and Walleye. Designed with a thicker section in the mid of the bait as well as one end offering more durability when wacky rigging or nose hooking the Pro Leech provides versatility to match the conditions and presentation when met head on. What is the true secret behind the Pro Leech and all X Zone baits? 100% True Hand Pour Means More Naturally Moving Baits. Using this technique to make the baits takes longer than traditional injection molding, but the end result is a bait that is durable yet incredibly supple, which is key in duplicating the subtleties of nature.
