I wasn’t expecting the Flipside, but I played it and had to have it. Oops, that ate into my budget… $20 gone. Got the Raptor I wanted, angry at that because of the gunked up bearing, but that’s an easy fix, so loving the Raptor. The part I really hate is the Baracuda. I played that and now I gotta have that. I hate the fact I didn’t have money to walk away with that one.
Duncan makes a lot of good stuff. The Flipside with the stock concave C bearing works great and is unresponsive. FLip the spacers and pop in the included A bearing for responsive play, so they say. I bet cleaned, it would be unresponsive. This unit also uses the Duncan silicone pads like in the Raptor and others, and so I am assuming it could take flowable.
