Z slash is swing faster,bs is aerodynamic,is cut air.

Hahaha...slayer z is slim frame..bt aerodynamic nt slim,its widebody or is aerodynamic.

U can try to see d pic z slash and bs10 frame..u wil notice that bs frame 2 side is sharp...then z slash is arn like box shape..slim frame is d frame heigt more short.

Ok...if u put d 2 racket 2gether,then u look at d side of that frame.do u notice that z is more slim..bt d 2 side of that frame is box..then d bs frame more fat..bt d 2 side at d frame is sharp shape..so can cut d air.box shape cant cut d air bt bcoz slim u can swing it easily.

you should swing it. it's very head heavy according to reviews. unless that's a fake

can consider yonex ultima series

Bro,

anyone use bg6 before?

yea it's string. durability and feeling compare to bg66?

of course stretched longer is more painful when hit our hand
but..more painful means?

from what i see, it's the opposite (no offense fantasia bro )
u pull the rubber band a little bit which illustrate the string movement when the shuttle hits
higher tension will have smaller X while lower tension will have bigger X

it's like jumping on bed(low tension) and floor(high tension)
bed will allow higher jump (means more power)

that's the theory that i understand

btw, good effot to explain the 'trampoline effect' bro fantasia
sorry if it is not what u're trying to explain

he did mentioned to pull the rubber band X cm same for experiment 1 & 2. This make the X cm is the constant figure.
When you stretch the rubber band longer a bit, you will need more strength to pull the rubber band to X cm.

Stretching the rubber band = tension
Pulling the rubber band = strength / hitting force
In short, the higher tension of your racket the more force you need to make stronger hitting power than using low tension string.

I just give a guess on what he mean.

your example seem like didn't hit the point, we are talking about difference rubber band now, rubber band A is 24lbs rubber band B is 28lbs, if you use N strength to pull the rubber band A to reach X, you need N+M strength to pull the rubber band B to reach X, or with N strength only you can pull the rubber band B to reach X-Y distance only.

smash power not depends on X only; a racket B 28lbs string with X = 1.8cm only could be more powerful then a racket A 24lbs string racket with X = 2.0cm, if racket B can get X = 2.0cm also then sure a lot more powerful then racket A.

indeed your example is more suitable to describe shaft stiffness, if use N strength to band the racket shaft, the smaller the X value mean the stiffer the shaft; e.g : racket A modal 1, X = 1.0cm, stiff; racket A modal 2, X = 1.5cm, mid-stiff, racket A modal C, X = 2.0cm, flex. . .

between bg80 and bg66 string,which produce more power if use the same tension?

because a new shuttle has the best flight ma..sure they wanna play with a better condition shuttle. and most importantly, it's sponsored
when they change, the shuttle is just slightly imperfect. we can still use them to play a game before it's totally unplayable..maybe 2 games too
althought the AS30 can last me 2 games, the feathers are curly here and there a little bit but NO broken feathers
if it's the No 1 Tourney, feathers broken until i dont wanna use it for warm ups..no eye see

Get tantrum 200! With that budget, and ur double play. its the best solid one. clashes? hahaha... i have clashed 3-4 times(hard) but the paint also didnt chip out. i hit few times on the floor coz frustrated, but yet, paint job is still excellent. i think if i remove my string, it looks brand new. haha

its very damn solid racket. apacs tantrum 200, u wont go wrong with it. hehe
