I shot the Revolt X, Revolt, and Solution SS quite a bit before ordering a Revolt. I still question whether I should have gotten the Solution SS.
Here's my take:
All these bows were on comfort setting.
The Revolt X was the fastest and had the best string angle. Overall it was my favorite to shoot. However, I have a weird anchor point and that with heavy clothes in the winter made me want a longer brace height.
The Revolt and Solution SS are very similar. The Solution SS is a touch slower and also has a touch shorter brace height, compared to the Revolt. I ordered the Revolt based upon that (win -win). However, the Solution SS is 0.4 lbs lighter. Also, the SS has significantly larger cams. This will make the string angle slightly better (the bigger cams are like adding around 1.3 inches of axle to axle length over the Revolt). Whether or not the string angle will make a difference probably depends upon your draw length and shooting style and whether you are stickler for getting your nose on the string.
I have a 30" draw length, and the Revolt is short for me. I got around that by serving the string below the peep and putting a large kisser button there. I now touch my nose to the large kisser button.
I still go back and forth with whether I made the right decision. It was a pick your poison among similar poisons situation.
The Solution SS is slightly smoother than either the Revolt or X, but all of those bows are ridiculously smooth so I didn't even worry about that. From what I've read, the Revolt is harder to let down smoothly. It is a hard bow to let down because the letoff is so high and valley so large. I feel like I could hold that bow back for 5 minutes, and my bow arm would get tired of holding the mass weight of the bow before my draw arm would get tired holding it back.
