hi fellow lane masters junkies I need some advice on a ball choice.  ok I recently picked up a used sting and bpr and would like to know if there's a big enough of a difference between the two to keep them both I also have a wcpp wc hornet surestrike and big r bang. I have a buyer for the sting so I just can't decide on weather to keep it or not so if anyone can help me out I'd appreciate it  thanks
