DD has a Wintec 250 that she has had for a couple of years. It has held up really well and she loves to ride in it. It is time to get a larger saddle and she would love to stay in a synthetic. Any comments on other brands? I believe HDR makes a synthetic as well as thorowgood butr am not familiar with either brand. She is looking at the Wintec 500 but would love information on the others as well.
