There are some that are 4" up to 24". 4,6,8" are castable. Those larger are usually trolled on 50 lb test or more. I use 100 lb braid to troll them since they are so expensive. Couple of weeks ago at Amistad we trolled 4 rigs at one time. Once we had 1, 2, 3, 4 striper on all 4 rigs at the same time. It was exciting.
