I happen to know a guy that uses a round tube. It may be a personal choice.:rolleyes: I like the way fish cat#4 and fat cat sit so much higher in the water. They are just plain user friendly. You can see easier and when fly fishing, it is much easier to throw a line. I could be a salesman for these things. lol I have only been in a donut once and was basicly helpless compared to a pointed front. They still sell them, so someone likes them Wish I could be of more help, Mike
