i have the 4 1/2, 6 and 10 1/2 and they all catch fish. i sell a lot of the 4 1/2 to guys using on a shaky head. and i personaly been tearing up the bass with the big 10 1/2 in. also the plastic we use has action unlike any zoom trick worm. you can load up the worms with salt like zoom or leave it out and get some great action bass can`t resist. caught a 3lb 8oz bass today on the 10 1/2 in trick no salt. use to be a zoom trick worm fan. not anymore
