Minn kota trolling motors

Anyone out there have any experience with the Minn Kota Ulterra i pilot link trolling motor? I am looking on updating my bass boats electronics and have read reviews on the Ulterra. The reports are about 50% good and bad. Most of the reports are 1 or 2 years old, and I am wondering if Minn Kota has addressed / Fixed the issues - mainly with the auto stow auto deploy feature. I am also wondering about the optimal batteries to use as well as the "Quick release" optional feature. I am torn between the Ulterra, the ultrex, and the Terrova. All have the option of the i pilot link, but only the ulterra has the auto stow auto deploy, the terrova has an assist deploy and stow, and the ultrex has the standard Manuel deploy stow. Sure would like to hear from anyone with first hand experience.
