I got interested from the posts from the other guy, so i decided to try it out since it wasnt too expensive.
Bought it off taobao from a random store, pretty disappointed.
Balance point is ~375mm, exactly the same as my Ultralite. The Spark and my Ultralite also have the same BP.
The issue is the weight. All in (1 grip, strings, bumpers), it weighs just over 150g, for an advertised racket weight of 115g. For comparison, the Spark (115g frame) weighs just over 140g all in. And my Ultralite (135g all in advertised) weighs also just north of 140g. It seems like the Spark is the new Ultralite.
For reference, all 3 rackets were weighed with the factory grip and factory bumper, and factory strings for the Spark & Wingedfalcons, and 305 1.1 for the Ultralite
Im gonna just return this wingfalcons racket because its definitely not as advertised. I was hoping for head lighter Ultralite, but instead its just a heavier Ultralite.
I will try to hit with it tomorrow if possible just to get a feel of the racket stability and see if its at least stable like the vapors are
