I have to disagree with most of the above comments. I have a viento and the twitchin bar is much more than just gimmick. I use it all the time when fishing jigs, worms, and shakey heads. And to answer your question it is great for senkos. I have fished it on the same trip as a patriarch and a energy pt, and the Viento was superior to both. The patriarch was a bit smoother but the viento casts much better. I mostly use braided line and with this reel and line combo i can cast an eighth ounce shakey head jig around 100 feet. The magnetic cast control is the best i have found and when set properly i have to almost try to make it backlash. I would recommend this as a great reel.
