I’ve heard they’re useful. Any suggestions on ones to get, I’ve seen a ton of them on Amazon.
I've used them for two years and like them. However, this year with the hitting and pitching engines, I've actually been more successful without them.
If you're curious, I've used the galaxy (concave) and the battle royale nightfall (convex). Overall, you want to find what you like more between concave/convex and then what height stick you like. The battle royale ones are the same height, the galaxy have a tall and short (tall for hitting stick, short for pitching).
I use white Galaxy's, high rise on left stick mid on right. I find them a necessity now...
