Crankbait body size and running depth should be looked at as two different attributes for bass fishing. The Rapala Shad Rap is a good example. A perennial favorite during the spring or anytime shad are shallow, the Shad Rap ranges from 1.5 – 3.5 inches in length (SR04-SR09) and the body deepens as length increases.
Common sense says to match lure size to the forage but there are other considerations, such as bass activity level, position in relation to the bank or structure and time of year. Professional bass angler Terry Bolton shares some pointers on selecting the proper size crankbait for the conditions.
