Those racquets feel like hammers because the weight distribution is towards the head, it gives you extra power but also the feeling that the racquet is slow to maneuver, or even cumbersome. This is clearly not the best choice for a defending racquet, even if pros can defend with, I assume you're not pro
Yes you can use it to defend. I am sure anyone can use any racket to defend. Whether the racket is good or bad for defending, thats another subect.
Great diagram and I also agree with your later comment about choosing a racket to suit your abilities, not the other way around. Just one quick confirmation- when talking about the characteristics of rackets, what does hold mean? Does it mean control?
I suspect (and I'm not at all sure about this) it's something to do with stability and shock-absorbtion. That might explain why it's not compatible with head-light balance, and why the AT900P has a lot more than the AT900T (which would seem strange otherwise). The chart's been posted before so I'm sure there's a proper explanation somewhere.
U can use any racket,even tennis racket to defend.But if u ask better,then u should get a head lighter racket.If u prefer all round,then get the balance racket.If u prefer offensive,then get the head heavy racket.If u have a brand preference,than it'll be easy for us to recommend u.If not,then there'll be too many options..
Armortec 900 power is a different type of defense - slower racket but harder returns, meaning it gets past the front faster (thumbs up) and easily shifts the tempo.
