carbonex 21 special usage help recquired

I sold the racquet a long time ago. Get something new and better.

 

I totally agree with this. I think the cab21 special was only delivered in 2U. For 2U use the BG80. If it was a 3U version, us a thinner string with more repulsion power like the BG85 or BG66. On my 2U cab21's I have BG80's. On the 3U version the BG66. 24 LBS is almost the limit for this thin and older racket.

 

22 lbs on the cone is recommended tension and covered by warranty
however, usually a racket can hold more than that tension

if you are afraid 24lbs would harm the racket, then try 22lbs

 

BG65 is very durable, but has little repulsion power so feels very dull. The BG80 has a higher rate of repulsion. Stringing it at lower tension usually has more power, but less control. If you string it at higher tension, the control will be better, but the 'catapult effect' will be less.

 

I'm not very knowledgeable with string (so please correct me if I'm wrong)

the string is pretty important because it is the point where your racket contact with shuttle
no matter how good the racket is, if you choose wrong string and tension, you will feel it
numb feel, not repulsive enough, not lively, cannot generate enough power from it, etc

string divided into tension and thickness (CMIIW)

lower tension usually more forgiving because of larger sweet spot
and if you are a beginner or lack of power, lower tension help you to bring out power (since there is trampoline effect)
lower tension also helps to maintain the string (string durability)
however, for few shots that require precision such as net play and bird placement, lower tension makes it worse because you need to count the trampoline effect

high string tension is not forgiving, it is because higher tension means smaller sweet spot
it also give better precision in net play, or bird placement
and also the string feels more repulsive
if you have power and right technique it would be better to choose higher tension because you want to trade your power with more precision
it also produce higher / crisp sound which is pretty nice to hear
however, higher tension means your string is tighter and it would snap easily (depending on the string thickness though)
and without correct technique, higher tension would be a disaster for you since they are not forgiving and you cannot generate power from it
many pro players use high string tension, such as 28-36lbs

string thickness:
thicker string means the string can hold higher tension and has good durability
however, it feels numb and less lively

thinner string, would give you better feel and repulsive
however, it cannot hold high tension, and has bad durability


choosing string tension is matter of your power and technique
choosing string thickness is like trade off, better durability or performance

 

Tried to tell in fewer words. I agree with all except the sweet spot section. I don't think the string tension influences the sweet spot and the forgiving properties. It's a design specification of the racket.

 

I know few people who uses the racket for few month only. After that its either they sold it or just get a new one. I've tried this 21 special, and personally I think apacs clone are better racket. Carbonex 21 special is no where near the carbonex 21 sp. The 21sp is still among the best racket to play with. If you still need to play with the racket then you might need to experiment with the right string, string tension and the grip size. Happy badminton.
