Not going to argue for asyms, to each their own.
However, for the OP, its is important to note that not all asyms are alike. Those that will drive on the deepest reach, won't fly on the beam and vice versa.
Yes, ultimately the asym set up is much cheaper, which also works for me. I so rarely feel the need for a spinnaker
at all. I haven't even sprung for one this boat yet. Of course, I did price one up and at $6k for the sail alone, I'm still pondering.
