I like hyperblade galzzly but other than that, not really. I've only got that and hyperblade Master Dranzer (still have the box, but it's assembled).
Mm, that's a pretty recolour.
Oh, I got my takara Beyblade Spin Up Book. It has a bunch of crazy customizations in it including a different setup for 4 balls in mbd (which is easy, just put two in the holes either side of the tip, they stay nicely yet are easy to remove, and you could manage 6 like this), it also points out the holes in ACB base and Grip Base can fit balls (though they are significantly harder to remove, I've done it before with grip base, I had to loosen the tip and launch it to get one to fly out.)
The most interesting one (and actually the reason I bought the book) is storm grip with an upside down tip (which is impossible without adhesives of some kind (glue/blut-tac) but blader dj looks pretty darned impressed by it), apparently that was as an antidote to the fast wear of the tip (it actually makes for an insanely fast, powerful, and hard to control attack base, haha). I'll try and scan it later on, and upload it somewhere or other.
Also a whole bunch of stuff swapping rollers, wings, and bound parts. Apparently the bound SAR's were fragile because you could actually break them apart and put them back together, but still, wings snapping off like they did, seems dumb, but then, I guess if you have a couple of broken ones you could Frankenstein a whole one together or something.
As I said, I will try to scan the whole book, hopefully the publisher won't mind, but yeah.
Oh, it looks like it originally came with a red Auto Change Balancer, at least, there's one pictured on the cover and stuff, but I could be completely wrong.
They released 4 of these, as far as I can tell, I have volume one (which has all the numbers series (inc. Driger S/Dragoon S). Volume 4 Contains the V2 Series and is very hard to find, Volumes 2 and 3, I forget what they cover, but they're still available and I might pick them up when I can spare the cash, because despite being in japanese, the presentation is nice and very unique to someone like me who has had limited exposure to similar literature, and I would frankly love to own more, and see what they did in later books.
I'd actually love to see some of these modifications legal, though perhaps not the ones that result in permanent mutilation such as an "always sharp" ACB mod which involves cutting off the clutch part. But things like the dragoon S upside down tip and even one without a tip, and other tip swapping stuff that was apparently legal (not sure if this book covers it), though, I honestly doubt this book is going to change our rules. It'd be cool though, and add a whole new level to the game.
Some of them are straight up normal customisations, too. Also, apparently Knight Dranzer's AR was actually good when it was released (not from this guide, but from what I've heard from a couple of people around back then).
There are also a weird weight disk that I don't recognise, it looks like a thicker Wide Survivor, but it's not a bearing gyro WD. As I said, there's some crazy stuff.
There's also some info on older accessories and stadiums, so that should be nice
