My company is Storm....I also throw Roto Grip, but they're both made by Storm, so I figure it's similar to having just one company. I have been using just Storm for a few months now, and have been having great success with them. 1 300, 1 800, and two 11 in a rows, plus my best score in a PBA regional so far with Storm. They are matching up very well to my game, and I feel they have excellent customer service. I've tried just about every other company, with the exception of Visionary I believe, and while I've had a couple Storms I really didn't care for, overall they make a wide range of hard hitting equipment.
