If you're only looking to keep one board around for everything, a 160 is not what you're looking for. With your specs on height, weight, and boot size you could go as low in size as you wanted without giving up too much in terms of response. Rocker also allows you to downsize your board size around 3-5 cm, so riding a board of that size would be a little crazy unless you're only looking for a pow board or to just bomb runs. It will not be fun in the park I can tell you that. I would wait on buying it and find something smaller that fits your specs better.
