Walker Downrigger-Tilt Base + New Style

[dctaz37]

I picked up 2 walker down riggers with auto-shutoff and 2 tilt bases. One was a demo unit so new but missing the power cable but is the same style as the two on my boat. The second one is new in the box but the style is a lot different.  It has an extra pulley block, bigger magnet and a protective steel flex tube over the last few feet of cable.  My questions are : are the tilt bases worth installing? Advantages/disadvantages? Not sure on the new down rigger, anyone have experience with this style? Advantages + disadvantages? I've attached a photo.
