slim jims all the way!!
Either of the Woody's Dual Runner products seem to perform better than the Studboy "Deuce Bar" I had no luck with those and have a nice lightly used set for anyone that wants them. I have said it before, even though they are more expensive than stock or entry-level bars, the Dooly is the best bang for the buck to help out stock Yamaha skis without replacing the entire ski.
There are better options of course, but for the price, the bang-for-buck is pretty darn good.
