The Luxilon Big Banger ALU Power Ice Blue is one of the number one strings on tour today. Combining great durability with impressive power and amazing control, Luxilon has changed today's professional tennis forever. The co-poly with aluminum construction is a significant improvement over the first generation of polyester strings. The aluminum present in Big Banger ALU Power is unique to the Luxilon line, allowing greater repulsion and a softer feel. The co-poly construction allows the combination of material properties rarely seen before. In this string, it combines improved tension maintenance and provides greater elasticity for more power. Players are able to take full cuts while still maintaining a high level of control thanks to the generous spin potential. ALU Power is best suited to the player that prefers the baseline and takes fast, full swings looking to generate power and spin. Also available as Luxilon Big Banger ALU Power Silver.

"awesome string"
"This is a great choice and a used by many who play on tour. I have persuaded a few of my friends to switch over the years, they all liked it. It will put sizzle on your strokes."
"Great contact on top spin and slices. The blue strings look cool with Babolat Power drive"
"Great string,no movement at all,even after hard hitting. Lot of power descent top spin. played 2 weeks ,no loss of tension. If base line player with long hard hitting game this string is for you."
"Love this string. Im a 3. 5 flat-ball hitting player using an 115 sq. in. Prince racquet. I can hit all-out and most of my shots will land near the baseline. My racquet is rated 65 lb+/-5 lbs. I request at 67 lbs and the stringer deducts 10% so its strung at about 62lbs. The string adds more power, some topspin to my game. Touch, not so much. Although the blue is supposed to be the same as the silver version, the blue feels softer and is easier on my wrist. Also lasts a long time, for me 6 months. Yes it does lose tension, but my game seems to adjust to it."
"These strings were superb for touch especially for a polyster strings and the durability was insane. In my opinon, better than pro hurricane tour, rpm blast, solinco tour bite soft all of which I broke within 6 hrs of play time. Also these strings were very playable and did not have as much of the typical dead feeling of polyster strings and it also allowed for fast swing speeds without fear of trampolining the ball out. Overall, this was truly an amazing string. However, one thing this string lacked was spin potential. I felt like this string put considerably less topspin/slice than I would have liked."
"These are the best strings. Ordered them from this website and was very pleased with the service. Strings arrived very fast. Customer service was great, answered all my questions and were very helpful"
"Good product"
"Great strings. Good strength and is holding up longer than I thought it would. I always use this string so I would recommend this to everyone"
"Great durable strings. Enjoined playng with it. Great fill, good control. Lasted long and preserved tension. Would definitely recommend."
