We were using a ProPride 3P, so like the Hensley, there was no grease problem. But it didn't work out for our TT's design and we now have an Equalizer. The bars are clean, but I have to deal with the grease on the ball mount. I put a Walmart type bag over the ball and secure it with duct tape. It now comes in a gorgeous array of colors. I chose grey. Anyway, the bag is disposable, and with a minimum of caution, I remain grease free. BTW, anyone want a 3P at a bargain price?
