I don't disagree with the "go biggest" statement per se BUT space is REALLY limited on a 14' Lowe 1440. I have 2 Piranahas currently ---- 1 for the transom and 1 for the trolling motor. I expect to upgrade the boat to a 16 or 17 with 60" bottom next year, but again, not a lot of room. So, given the "room" constraints, what do you think? and, Bird or Lowrance?
