After having done some shooting over the holidays, I'd like to give some short assessment.
Overall, not much difference to other carbon arrows, except for the length/weight combination.
The shaft is very lightweight, and thus behaves quite "nervous" in a light setup, i.e. sensitive to unclean release.
Such errors exhibit in a visible fish-tailing.
I didn't do an explicit robustness test, but IMHO this is a target arrow.
I don't expect it to survive hits on stone or metal surfaces.
Which means, this is not my first choice for 3D parcours.
What I didn't like: the diameter of the insert rim is more than 1mm larger than the shaft diameter.
This exacerbates pulling the shaft, and increases wear. I don't know if the insert comes from the manufacturer or the dealer.
I had ordered the shafts, with nocks and inserts included.
The initial idea was to use it for flight shooting, but that didn't play out so well.
On every try, the light 240gn arrow was outperformed by a "standard" Easton Inspire 560, (350 grain), with 2.5" parabolic fletching.
To give some results:
Alibow Qinghai, 25# @28":
Maximal Carbon Edge 6.2 (240gn) : 187m
Easton Inspire 560 (350gn) : 193m
White Feather Forever Carbon, 30# :
Maximal Carbon Edge 6.2 (240gn) : 212m
Easton Inspire 560 (350gn) : 122m
White Feather Forever Carbon, 35# :
Maximal Carbon Edge 6.2 (240gn) : 225m
Easton Inspire 560 (350gn) : 250m
The distances were measured with GPS, which showed an accuracy of +-3m.
All shots had been done in about 30 minutes, including measuring and arrow recollection.
Tried a Forever Carbon with 40# as well, but with results very similar to the 35# bow.
I think I don't manage a clean release with this draw weight yet.
And finally I did some speed tests with quite interesting results.
Using the Bowometry smartphone app, this proved to be a bit difficult.
Even under moderate outdoor wind conditions, the app immediately "detected" a shot, with ridiculous arrow speeds (200...400m/s).
Thus I tried indoors, kneeling to shoot between the roof slope and a smokestack, the only place wich allows for the minimal distance of 10 m ...
Even then, I got a >400 m/s result occasionally.

To be honest, I think one needs to take this numbers with a grain of salt.
If wealth befalls me anytime soon, I might get a real ballistic chronograph ...
