I grew up skiing in Austin at least once a week and joined a ski team in college. With that being said, I haven't skied regularly in about 7 years. I have been going out on the lake more recently and would like to have a waterski to get back out on (hopefully I will have my own boat in the next few years). When I do go out, it is ALWAYS a wakesurf boat on Lake Austin or Travis, so it's reasonably choppy. I can't decide between a Radar Butterknife or Union. I'm worried that the butterknife might be too much of a beginner ski for me and that the union could be difficult to get up on behind a wake surfing boat.
