Funny you should mention that about kastking. I bought a lews smash 7’2” MH combo from bass pro about a month or so ago. They put 15lb mono on it. My brother n law & YouTube walked me through dialing it in. Knock on wood Ive not back lashed once. Two weeks ago I bought a kastking royal select 7’ FMH & paired it w/a kastking megajaw 7.2 & 30lb braid. I can’t not backlash with it.
