Doing a boomerang you will be a spintop EXPERT in the eyes of any non player!
With pass of years, I have discovered that this affirmation is true.
Btw. Whence comes the tittle, the name of "boomerang" for this trick? I am more than 44 years old and as far I can remember, since I was a little kid, this trick was already called like this way.
Does somebody know something about this? Any help, contribution or cooperation is previously acknowledged.
