Anybody experience with the low end Li-Ning? I mean Aeronaut 4000, TC20 or Calibar 009 or 200? I'm looking for a birthday present for somebody who don't play a long time and start to learn the right technique. I guess that the flex can be supportive.
Keep on forgetting to reply to this.
I brought a 4000B as a potential backup to my 7000B.
A couple of things I noticed.
During stringing there was a noticeable racket head deformation during the last cross for the 4000B compared to 7000B. (Might be a one off, but something to consider). It's something I notice on cheaper rackets.
Feedback wasn't as great. Could be down to shaft stiffness or materials.
The 4000B aeronaut system is different to 7000B. 2 slots instead of 4 and possibly bigger.
Base paint job seemed as good as 7000B, but decals details seemed fragile. Again might had been unlucky with the a mishit.
Conclusion
Was too different to my 7000B, so sold off the 4000B while it retained it's value.
As for a racket in it's own right, I say it's heavily dependant on the prices you can get it for.
Currently the 4000B is £85 and I believe the 7000B is around £140 in the UK. At £85 i would be looking at other brands like the new Adidas range. For the 4000B to considered in terms of price, I would say it should be at least half the price of the 7000B.
