>>There is a guy in our fleet who started on the Taipan 4.9 with spinnaker for the same reasons you state. He sold the Taipan and bought the I-17R and told me he likes the I-17R better. He is the only one I have heard of that has owned both boats. Hope this helps.
I thought J. switched because he wanted to get into OD fleet racing instead of PN racing and the I-17R definately has a better class thing going on in the great lakes area. A good reason to switch, I think.
However I would be surprised if he sold the Taipan because he disliked it as a design.
