Cold water tactics

What methods do you use for the colder seasons? Ive done awesome all year in a bunch of settings on a mix of a lil corn starch, panko crumbs, stawbery jello mix, and whole kernel sweet corn made into a dough and packed on the hook inna ball? Also done ok on a worm and anis oil.. I've never tryed hair rigs, boilies or pop ups? Do you think I need something to present higher up twords the surface or is it cold enough to really matter? Thanks amigos
This is on the Willamette and tributaries around the eugene area. Its been a mild temp so far this with few nights below freezing for the most part.. What setups do you guys run?
