Oh my god these things!
I got into them after beyblade. I really liked them but the game itself kinda sucked compared to beyblade, and they were difficult for me to put together and maintain, I think I lost most of my parts (there were so many tiny gears and washers), though I still have my favourite.
I always went for one that didn't spin around everywhere but went straight, and focussed on parts that provided that, and mainly used the stabbing/pushing weapons. I recall using the beetle wheels at the front and these dragon ones at the back that look like they would really not assist with the straight movement at all but whatever.
I used this red body that was really spikey, it came with a grey and purple weapon that I used for a while before swapping to garuda phoenix's weapon.
I had the stadium, which has since been binned by my mother along with my old plastics stadiums (beystadium II and spinblaster)
I also remember really wanting a particular green one, but it wasn't the dino phalanx or the one from before that (which I had, and man that thing was terrible).
But yeah, these never took off here (though they were the next fad after beyblade (as indicated by whoever produced the fake beys sold at red dot here going on to produce fakes of crush gear)).
