nugg u have ur finesse gear for bream, if ur looking for a heavier rod look at the t,curve. yes u camn land them on light stuff but nomatter what anyone says if u want to target jack uneed the gear to stop them (unless ur catching them on sand flats) its depending on the structure u fish and if its bad country and ur doing more livebaiting u do need a broomstick rod.
any serious jack fisherman will tell u that u need much more then a 6kg rod to succesfully target jack.
