We used Rawlins balls against Aiken & it wasn't too bad, considering the brand we're dealing with.
I still don't agree with making it mandatory, but I understand it from a business standpoint (they signed an exclusive deal so yeah, we have to use their gear). I don't know if there's enough weight to merit the HSL eliminating the mandate for us. Plus, it's still South Carolina HSL we're talking about here & we know how they are when it comes to our sport
