The direct connect mounting system to provide a more natural feel when turning the ski and while also greatly reducing the weight of the ski boot.
Disclaimer: This 2015 product only mounts on a 2015 or newer HO waterski. If you are looking to buy the new 2016 HO boots for an older HO waterski (or a non-HO waterski), and color match it up to one of these new 2015 HO RTPs, you are in for a surprise. HO makes an adapter plate to mount your boot on a 2014 ski, but they did not make an adapter plate for this 2015 RTP. You will have to buy the Classic Black RTP (part of the HO Animal Binding line), or find an older 2014 RTP binding in stock, but a 2014 Rear Toe Plate bindings are becoming scarce because they don't make them anymore.
