In 2003 Johnnie DelValle (JD) became the first player to ever win the regional, national, and world titles all in one year. Capturing those titles with the HitMan he then brought to life the X-Con built to 'grind' and 'stall' with the first streamlined large aluminum weight ring shape from YoYoJam. Fast forward to 2011. The ability of the yo-yo player has reached new levels and with that comes an evolution in yo-yo design. In the tradition of the HitMan and X-Con comes The X-Con Professional -- the next level of yo-yo design created for the future of technical string trick play. The X-Con Professional is crafted in an undersized shape and features hefty precision-machined bronze weight rings precisely placed for maximum stability, spin, and control. Learning intricate strings tricks has never been better and the undersized smooth shape means it as comfortable as a yo-yo can be in the hand and on the string. Whether you are just starting out or getting ready to win your first world title, X-Con Pro will help you get there. The complete package X-Con Pro is built with the Solid Spin Axle System and includes the YoYoJam responsive beginner's bearing as well as the SPEED bearing to allow players to easily move from beginner to advanced unresponsive play. Carbon fiber caps and the brilliantly designed body of the yo-yo give the X-Con Pro a finesse others have yet to achieve. Built by the player for the player and JD approved.
