i use both for both. it really depends on my mood which i use. when its windy i grab the spinning stuff if the breeze is gonna be in my face because casting light stuff into the wind on a baitcaster is no good. when its cold i go with spinning gear. i dont like the mist in my face/hands when its cold. when its warm though i like it so the baitcaster is the rod of choice. anytime i use live bait its on a spinning rig as well, too much snap during the cast with a baitcaster for live bait. any slip bobber fishing is on spinning gear as well. i like the control of backreeling on a spinning set up over the drag on a baitcaster as well. i can cast light soft plastic setups about the same on either rod so thats a wash. i switch it up because i like the right handedness of baitcasters but i have the handle on the left side of my spinning setup. allows me to fish non stop all day and never get tired by just changing rods.

i mentioned baitcasters a lot in this thread because we were talking trolling. i prefer the baitcaster for trolling because i have the drags tightened all the way down on my spinning stuff. i like the backreel. for trolling you need the drag.
