Really? Houser's own stems the splines twist, don't think I would want them replacing splines if their stems do the same thing.
I've twisted splines on stock, Houser, ars-fx, Burgard, Lonestar, and some stem called a Viper that I cant remember who made. They all twist at some point... But Houser is the only one I found that would replace the splines on their stems. Burgard may replace his too, but I didnt have time to wait to have it done so I just bought another stem.
Run whatever stem you like. But if you're running a good stabilizer, have strong tierods, and you hit something hard enough you can bet the stem splines are going to twist, no matter what stem you're running... That's just one of the design flaws on the Yamaha.
