Premier Control in short
Prince Premier Control is the control version of the Premier multifilament line. A firm Tri-Core center sits inside soft fibers, which Prince sums up as phenomenal comfort with controllable power. It costs well under most premium multifilaments and comes in three gauges plus a reel, which makes it a practical soft string for juniors who restring often.
Power Fiber Pro in short
Volkl Power Fiber Pro is a firmer, more controlled and more durable version of Power Fiber II. Bigger filaments of a firmer polymer give it more control than a typical soft multifilament, while it still absorbs shock and vibration. Reviewers rate its power and feel above average and its spin below average, and durability reports are mixed. It comes in four gauges and several bright colors.
