I felt the same way as you...for a long time. Then my friends had some different chalk, I thought they were crazy, chalk is chalk. A good buddy gave me a box of Blud Diamond...It set in my case for a few months and finally tried it. It coated better than Masters and even though chalking often is a habit, it was better chalk than the Masters. A few weeks ago I ordered some stuff from Seyberts and bought the Predator and Balabushka chalk and decided to see for myself which one best suit my needs. I'm going to start playing with the Balabushka chalk. Maybe it's a mind thing, but the Balabushka chalk stays on better and longer. I still have some Kamuii chalk, but in my mind, $30 for a piece of chalk is crazy. Yes, it's amazing chalk, stays on for multiple shots, but at that pricepoint, I'm no champion and a piece of chalk isn't going to make me a champ.
Spend $25 and get the Predator, BD and Bushka, test them out yourself. If they help your game, even if mentally, it may be worth it.
