Well I will throw my two cents into this now. I have had both systems, yes the feel of the cables is different, but with anti feed back dual cables, you loose most of that feel anyway, as when it is working correctly, there is no feed back. What I discovered, was that in a short time, with both the boats that I had with it, they stiffened up fairly quickly, to the point that it took a very good grip on the wheel to make any sort of big turn, not good for me, as I have tendinitus and or carple tunnel, it has cost me much of my grip over the years.
I am now on my third boat with Hydraulic, I have not yet experienced as much as one issue with it. I also am VP of the South Dakota BASS federation, and go to all the divisional tournaments. this is my 17th year of that, in that time, I beleive I have only seen one issue with the hydraulic systems, and that was a person who did NO maintenace checks on his boat ever, I did hvae to add a bit of oil and bleed it for him at that time.
I have never had my boat in the ocean, but our resevoirs on the MO river hear are big and nasty, I have canceled tournament days several times for that. I have also had my boat on Mac's St Clair, Erie Twice, Huron, Michagan several times, I have seen some very nasty water, and again, never had an issue. I can turn it very easly with one hand, not needing a harsh grip ever, it is very comfy to operate with the hydraulic, I would never want to go back to cables and the strength it takes to operate.
If there is one small drawback to hydraulic over cables, our lower reseivoir, we do a lot of shallow water, tight turn navigating, the cables do turn the moter quicker with less wheel turns.......but I gladly work with that over the hard turning cables.
