The MK ipilot link motors paired with HB G2N or G3N units are an incredible setup. The link opens up a world of features that come in pretty handy pushing, pulling, and staying put over your favorite structure. The new MK motors have the option of getting the Mega DI xdcr built into the motor which is very nice. You can spend thousands on this stuff, just ask my wife! You are right, there are many many ways to go and I spent hours reading and researching before setting my boat up. and just when you think you got it figured out, something new comes out!

My current setup is: Helix 9 mega DI G2N on the bow, Helix 9 Mega SI G2N on the console, transom mount 360 transducer, and terrova ipilot link. All of these are networked together through a HB network switch. Oh and a Garmin 93sv with panoptic livescope transducer on the bow also.

I can only comment of what I have used an I personally love the Birds and MK paired up. I have no issues with my terrova because I almost never use the foot control and the cable on the Ultrex used to get in my way while spider rigging, but my buddies love the Ultrex. So most of the decisions seem to be personal prefrence.

Good luck figuring out what you want, and just to help you spend some more money I have to say the the Livescope is probably the most incredible thing I have ever used in my life and the 360 is awesome finding structure and coutours in all directions. Definately worth taking a look at!
