Since you’re looking for something to “set” your preferences(that won’t happen), let me give you a few features to think about.
1: Shape. With so many shapes, figure out what you think you like best. I like V-shapes. The Chief is V-shaped. Still, there’s plenty of good H-shapes, and whatever you call the shape of things like the Barracuda, well, that’s some nice stuff!
2: Grinding. Think about grinding. You may not need it now, but you might want it later. Think about what grinds you want to get into. Finger grinds are fairly good, most yoyos can do that. Thumb grinds are easier with an IRG. Based on your skill level, I wouldn’t worry about finger spins. The Chief can do finger grinds good, but is a bit tricky to do IRG’s, but it can be done just deeper into the rim due to the “Chief rings”. The nub in the center interferes with finger spins. If you take a smaller size, the Arctic Circle resolves that problem… mostly. That portion of the rim is convex: it bulges out. On the other hand, stuff like the YYJ Titan3 and the C3 Electric Flash and MoVitation are excellent on the grinds.
3: Maintenance. Mostly I’m referring to response pads. I prefer stuff I can silicone, but it won’t prevent me from buying something. I’ll just stock up on pads. Any CLYW can be siliconed. So can many other yoyos. Just think how important DIY is and then skew your order accordingly. There’s no shame in buying pads. Bearings can be cleaned or replaced.
4: Experimentation. This is more trivial. With this kind of money being spend, maybe you want to experiment with bearings, but if the Chief is what you’re after, I am pleased with the flat bearing mine came with, but they now ship with CenterTracs. You may wish to also experiment with different strings. I’m really liking YoYoStringLabs Type X and Tristed Strings Trixtra. At the same time, there’s nothing wrong with more affordable strings like Kitty strings and YYE 100% polyester bulk. There’s many other strings work trying. I got some Jack Rabbit strings at 2013 Nationals and I’m liking them.
5: Consider a pouch or holder or some way to protect your yoyo. I just like to keep my stuff looking nice whenever possible.
Considering you might get nailed hard for international shipping, you don’t want to make separate orders. Lump stuff together so it’s one box.
I can’t find fault with the Chief. I do feel that the C3 Electric l Flash would offer everything you want, need and save you money and still leave you in amazement. It’s certainly an item you will want to keep in consideration.
