Most Engine Gears are pretty useless, Dragoon GT's engine gear was one of the better ones, but generally, they're too tall, and having such hefty tips slows them down. I do love both dragoon and dranzer gt's AR's though.
Storm isn't super hard to find, and you can always by one with worn rubber and replace the rubber with that from a sonokong gold one (legal, but the gold parts tend not to fit with regular ones).
The gt's are some of the rarest beys, so yeah.
Plastics tourneys can be held whenever btw, you could get some and organise one yourself without it being remembrance day!
Dragoon G's ar is great, though I currently love gt's, eight spiker is a staple part. 10 wide is handy. Base and sg are, like basically all eg's, lame.
10bBistool: still waiting on my bistool but there really are better beys. 10 balance is the part it's customised with tho.
Dranzer GT: it's upper attack, with a little smash mixed in. Check the "building a plastics top tier list" thread for the combo I nicked off.mc frown and use Triangle Wing on.instead of upper dragoon, I love it. That said, upper dragoon (kid/master dragoon) is an easier purchase, and often considered better :\
Bb 10 is fully plastivs legal, though tornado attack is more "realistic" if you like.
Wolborgs? Mkay.
Wolborg 1: Hasbro one had a wonky shaft and poorly angled tip, avoid it. TT one is possibly the best for straight up stamina zombies (bearing stingers shaft competes here), but is rather easy to KO. Other parts not worth mentioning at all, unless you really can't find a better base for the sg.
Wolborg 2: Rubber tip makes it hard to ko, using a bearing makes up for the poor stamina, however OS is a significantly greater risk here. Base is better than wolborg 1's, though dragoon v2 should be purchased for a serious zombie. Used in that dranzer gt combo I mentioned earlier, as it's the best base for that (dragoon v2's scrapes, etc). AR has some smash, but there are many better options.
Wolborg 3 (Uriel): Base is a mirror of dragoon v2's, gold plastic makes it fragile, not really a wolborg.
Wolborg 4 (G series): one of the decent eg's due to the exclusive survivor eg or w/e, which offers good protection. Would have been monstrous if it were compatible with zeus's bearing gear. Ar sucks bad.
I find burning cerberous's dual bearing sg is harder to ko than wolborg 1's sg while still having great stamina, and the slightly lower base (compared to dragoon v2's) is nice too.
Beywiki has loads of info on this stuff. Also, if you get into plastics, do grab a wide defence weight disk, you'll need that or wide survivor for a zombie, and it's an incredibly versatile piece.
