I use chinu's as a pennel as opposed to circle hooks also and they are excellent.
Been trying large 6/0 circle hooks for top pennel. Learned not so good from a drifting boat. However still in two minds about shore bait fishing for cod. I have been offsetting them and managed to pull in a couple of codling. One hooked through top lip and out of bottom lip. If this was a double figure cod in heavy kelp i guess it wouldnt of been shaken off. I guess circles will be in my box next season. Also been practicing braid on multiplyers. Heavy braid on multiplyers never been a problem for me but been toying with medium diameters to get good distance. And getting that balance that the braids not too thin for obvious reasons. Found a couple of braids which work and don't bed in at all. No need for a fixed spool for me. However it has taken lots of practice and wasted braid. Key is finding the correct braid and using mags properly.
