thats a big old bait for winter,not saying it doesnt work for you,i use around 14mm this time year a lot of 12s as well as you say at times tipped with a piece fake corn criticaly balanced seems to produce well as does popped up corn like anything really depends on the water we all learn quick what works on certain waters and what doesnt theres a whole world of presentation methods out there depending on the type of water/bottom coditions etc.had a lot of good results last year using zig rigs when all others on the lake blanking day to day in very cold conditions
big baits keep away nuisance
