there is the posibilaty of killin a fish from to mutch of a fight. science has proved that. but i think its only in extreamly long battles. i do love to fish with light tackle,but use your head you know. dont go huntin flathead with 6# test in a bunch of snaggs lol. you will not only loose the fish but leave him(or her) with a hook in the mouth.hope you guys dont take me the wrong way. these are just my opinions. if i had a problem with people killin fish, i wouldnt hang around the lake with crappie 66. lol just playin with ya crappie
