I personally altered the Surface to 1500 SiaAir - I felt at Box finish the ball may rev up to early and burn out. That's been my experience numerous times the last couple of years when a ball is at 500 Box. So at 1500 I felt I saw exactly what I hunting for and that this ball was true to what has consistently been my experience with Quantum's over the years (Smooth, Predictable, Hard Hitting). The Bias Pearl simply continues in that line and gives me an Asym that rounds out my 4 Ball Asym Bag (KingPin, Katana, Tenacity and Now Bias Pearl)
