I am looking for a middle of the road ball. I currently have a Redemption Solid now. I am considering either the Brunswick Uppercut or the Radical Squatch Hybrid

I just bowl league

Look at the Hero too.  All good balls

If you can find one in the correct weight at least. They were discontinued.

I've heard good things about the Squatch Hybrid being a pretty decent control ball.

These suggestions made here are all solid suggestions.  It would help if we knew a little more about your style so that we could get a better idea of what might match up.  If you are looking for a smoother earlier middle of the road ball a Verge may be a good choice.  If you need it a bit later a Verge Pearl or a Melee Jab Blood Red may be better fit.  You also could fair better with a lower differential ball with a stronger cover like the new Hammer Web Tour Hybrid.  I would suggest having your pro shop operator make a suggestion from amongst the choices mentioned or maybe post a link to a video where we can see you roll it.  Best of luck with your search.  Please don't hesitate to reach out to any of us here as there are a number of helpful longtime posters like Mr. Vance.
