Only the takara plug and play one has prongs. I'd really like one of those, or any left spin launcher that has a grip built in, because it's a damned pain to get left launchers to stay in most customize grips, and most of the beys I'd be using at tourneys would be left spin.
By the way, just rewatching an ep of the anime (Picking Up The Pieces, GRev), and Diachi is about to face Tala and wolborg 4, when Kenny is like "Here's a Customize
d Bearing Base, it's the key to beating Tala!". Though it's right spin (though to be honest right spin CBB may well outspin Wolborg 4) and he uses the stock SP which is just dumb, perhaps a secret message about what I always go on about (Wolborg 4 combos eat zombies except Customize Bearing Base because it's the best).
Either way, I thought it was pretty cool and wish they'd released a purple CBB, given how nicely that would match my attack combo (though it's really the blue cross survival sp that mess up the look, mostly).
