I know a lot of people dont know too much about Gamma, but it is very popular here in pittsburgh. The corporate headquarters are in pittsburgh, and it is great to know the company is in my backyard. All of the best players use gamma products in my area. I know a lot of people that use gamma myself. I must say, gamma products are exceptional, durbable, and perform soo well. I recommend gamma products to anyone. Where I hit, they have gamma balls, i was amazed at how long the felt held. They're overgrips are extrordinary and their replacement grips are the gold standard as far as I am concerned. I just wished gamma would become more popular because theyre product is top of the class.
