Need a little help on picking out a new trolling motor I know I'm going with the Minn Kota Riptide Ulterra 54'' shaft 24 volt 80 lb. thrust question is should I get the link or non link which is 500 bucks difference. I'm just not sure how much or if I would ever use it I am also going to get 2 new Hummingbird units just looking for some opinions so any help would be appreciated.
