Gary, my last coach (American) had a seat probably much like the one you have now. My Vision has an ISRI seat, which when I bought the coach, I did not think I would like. I would not trade back! It takes a little getting used to in that it seems to go down when you hit a bump in the road, and up when you pass over a concave portion in the road. Once you get it adjusted to your liking, they are very comfortable and seem to conform to your body. I think you would really enjoy an ISRI. Go for it , you only go around once, so why not enjoy the trip!
