This climb was inspired by the Momentus Swing Trainer which is designed to improve your golf swing. This climb will help you improve your fist jamming technique.
This felt considerably easier than Momentum Operator so I think calling it 11- is a bit generous; mid 10 might be more like it. I used exactly one fist jam on this route; I could see this being harder if your hands are on the smaller side.
Agree with Dave, probably a full number grade easier. There is a route in the Rossiter book, I think it is called "Altar" (5.10) that seems very similar to Momentus Fist Trainer, minus the bolts at the start....
