That’s up to you. Do you take your Chief/Cascade outside and play on concrete, in the grocery store, out and about, etc…? If you don’t mind playing metals like that in those dangerous “dingable” type places then I don’t really know what benefit you’d get from a Classic or a Surge. They are fun, but they aren’t of the same quality or caliber as a Chief or Cascade, but you also cannot expect them to be. The Classic/Surge/OneStar, etc…are mass produced plastic yoyos. They work great, and you can obviously win Worlds with one if you’re the right person.
I didn’t buy a Surge. I own a Classic and I play my OneStar a lot. But I play the OneStar when I’m out and about and don’t feel like dinging up a more expensive throw. Don’t get me wrong, I have plenty of expensive throws that are dinged to high heaven, it’s really just a matter of the mood you’re in I guess.
