Personally i have loved the srixon lvl 11 180cr per sleve balls since i made it to master.Still using them at tour legend and will most likely make it to champ eventually with them.Sure i dont hit sub 60's all the time like some of these guys.but itis possible to do decent scores with them.
They are very similar to the callaways for a fraction of the price 2 sleves for the price of one nearly.They will definately improve your game.And it is possible to occasinally win with these,but after all this whatever ball you decide to use.When you have used it long enough it will bring results.Practice practice practice.I have 50 other balls of various makes in my bag from expensive nike,volviks and callys..but the srixons are a very solid ball and i keep going back!
