If you see a solid it won't be at least untill the end of summer. I think it boils down to the sales of the Hyper Cell, which IMO is the best solid ball I have ever owned. The Sinister has its place in my bag, I usually switch to it when my Hyper Cell starts leaving flat 10's. Solid Sinister, this is a good question, my answer is the Hyper Cell is so darn good is it neccesary to make another HP4 solid? At this time I would say no. We will have to wait and see?
