You posted your question in the Storm forum,and your signature states"Storm (why throw anything else!) ".
That is why you received Storm/Roto ball suggestions.If you're looking at other ball companies,may I suggest you post your question in the appropriate forum.As for "not having enough hand" for the Natural Pearl,if you're bowling on a true dry lane lane condition, you need a ball to get through the heads cleanly.The NP will do just that.
The more I practice,the luckier I get.
