Yogi Bear: was very excited with this one because this is a 7 ply all wood blade. The blade is very beautiful to behold. Unlike the other adidas blades which i have tried, this is stands out aesthetically. the handle was beautiful designed and very comfortable to the hand. The handle is smooth, its narrower compared to its fibertec brothers but still very good to hold and its smooth. The handle is almost as big as the butterfly ALC or ZLC blades. The blade feels very good as i did my fh-fh and bh-bh drills. The Joola Samba+ was very bouncy on the Challenge Speed but I was surprised with the amount of control. This is a very promising blade since compared to stiga clipper cr this blade is:
Speed – Adidas Challenge Speed > Stiga Clipper Cr
The Challenge Speed is indeed faster than the clipper cr with a bit more solidity on the shots. Speed is lesser than the Ebenholz 7 or Rosewood 7 but you can still do power shots with speed of almost a fast carbon blade depending on your skill level. Adidas is right in labeling this blade as OFF+ but its control is like its an OFF- blade.
Weight – Adidas Challenge Speed < Stiga Clipper Cr
The Challenge Speed is not head heavy and feels like the 92gm blade is an 88gm blade. This blade is fairly balanced. Having a thinner construction helps the challenge speed reduce its weight.
Control – Adidas Challenge Speed = Stiga Clipper Cr
Both have good feel and outstanding control on the ball with the clipper cr inclined more on looping while adidas challenge speed is on loop drives and power shots. Far from the table, the adidas blade outshines the clipper cr.
The amount of vibration is minimal. The blade has good feel and it greatly helps the player control the ball especially on power shots. Looping is not a problem with this blade since it gives enough dwell time on the ball. It is compatible with both chinese and euro/jpn rubbers since I tested it with 3 rubbers.
All in all im very impressed with the challenge speed and among the adidas blades that i have now this is a gem. I would recommend this to intermediate up to the level of the pros since this is a very good blade. Also, i didnt have any problems using soft, medium soft and hard rubbers on this blade but i think this baldes go well with medium soft rubbers and hard chinese rubbers. Tenzone, P3 and Tenzone SF go well with this blade
