I will try to keep it short and concise. Just not so into long bull stories.... My personal take.
I believed the majority here are looking at this categories: Speed - Power - Defence - My Conclusion.
Victor Auraspeed 80X
-----
Speed Department:
+ Excellent manuverability
+ Fast handling
+ Swift with stability
Coming from a JS10 and BS12 user, speed is something we yearned for. The manuverability and stability is where 80X shine and perform so much better. Drop shots were fairly easy to execute while you are moving around the court gracefully. You will be in for a surprise how this thing moves so rapidly considering the tad of weight on its head. This is the first amaze...
Power Department:
+ Effortless Clears
+ Excellent Drives
+ Good smashes
In the power department, it was outstanding. Clears were crispy and direct (briskly). Drives were quick and stable (fast), and Smashes were pounding (downright power). The stiff shaft and tad of weight helps in the attack more than anything. I would definitely describe this as a Thor hammer rather than the WWE kind because the swing is quicker. This is a balance racket so, what's more to rave about. However, do note that the stiffer racket still requires your own contribution (ie. arm, muscles, back) to deliver. As for the second amaze, it will be none other than the recovery of full smashes. The dragging down is really subtle. Hence, you will always be ready for the next one until..... you or your opponent gives up.
Defense Department:
+ Fast handling in all aspect
I will only cover two important aspect, the smash block and smash lift (it include your smash counter). Blocking is a breeze, as long as u can reach it, the racket wouldn't let you down. It is fast enough to handle pressured situation such as under the armpit shots and shoulder smashes. Lifting is easy as long as your timing is right, the little head weight helps you to push even further. Thus, I do found myself countering a lot of shots wide...
Conclusion:
+ Thor Hammer
+ Quick handling
What else..... I round up with this -- 80X is an all rounder with aggressive and pounding capability.
