@Foobar I went with the 80Lb, 60In Riptide Terrova with iPilot and am very satisfied with it. I've used the spot lock quite a bit while fishing and spearfishing in the Keys and in 2' to 3's the 60In stays pretty much in the water and when it does lift out it recovers immediately.
I will say the factory mount flexes way too much and I'm already looking to fortify it by placing some "L" brackets on the forward "V's". The way it's designed only 4 of the pre-drilled holes are usable. I stuck my head over and watched it working in 2' chop and you can see it twisting and flexing. I imagine that would be exasperated with the 110Lb 72In model.
I mounted 2 29 series batteries in boxes in the forward section of the changing room which allowed me to use 8AWG wire instead of 6. I believe there would be room for 3 batteries in that location. I also placed a simple On/Off battery switch and 60Amp breaker by the batteries. I plan to run two of the channels of my 3 channel charger I installed in the rear battery compartment up to the trolling batteries and am also looking at potentially installing additional relays off the engine battery to provide some charging while underway.
Prior to drilling any holes I would recommend you use some sand bags or other weight to simulate the motor and batteries while your boat is in the water to check on listing and/or too much weight forward. Mine slightly lists to port now unless I also fill the bait well then it balances out. It is a bit forward heavy now requiring me to stand aft in order to get pooled water to drain aft.
