imo the best way to learn how to pull cranks effectively is to go to mississippi page pulling cranks 101. its got any info u want and those guys have it down to a science. i got on there awhile back and read for about an hr and the info i gained was priceless. me and my buddy started cranking this spring and we have been catching fish doing it no matter what lake we go to. study lake charts and learn where the drops and channels are and pull over those spots. if youre doing it right u will catch fish.
