I like my MF launcher grip and thought why doesn't i have a grip for my old plastic beys? Now i've got the answer for everyone who want to use his MF grip on old beys!! by taking of the spinning part (where you put the bey on) of an old launcher and a MF one and put the old one on the MF launcher and you can lounch plastic beys with a MF launcher. I will soon put some pictures here.
