I took the plunge! I ordered a 55# 45" with ipilot. I ruled out link because most of my favorite lakes are only on navionics and by the time you add in ethernet cables, box to connect it to my 1199 and 959 and the cost of lake master cards it was a big price difference. I run two batteries now in my 17' quantum fiberglass with my 40# all terrain and don't have any issues running out of battery in two days of fishing. If I switched to 24v I'd have to buy a different charger and isolator switch. Thanks for every bit of input. You all are the best.
