We use #4 and 2/0 red hooks made to our specifications. The trailing hook is approximately one inch behind the front hook. This 1" spacing increases your chance of catching the hard to hook and catch Kokanee Salmon. We've also added a #4 reverse (180 degree/Off-Set) tandem hook set. We use 10 lb test and a 30 inch leader. Each package contains 5 hooks.
