To quote Ivan: "a 2" hole is a 2" hole"..pick the slip on you like.circusnuts said:I posed this question to Ivan some time ago (thinking of trading-out my Yosh for the type of EVO he recommends) and he said when it comes to slip-on's it's basically esthetics, that in general there isn't a huge difference between manufacturers.
I don't think he's too far off.
