So if you want to truly see/feel/understand how much things have changed, I would recommend a modern bi-metal yo-yo. I have a very strong preference to the SF Bliss, but several people here have suggested the Hummingbird. IMHO I feel the Bliss has more character. Otherwise, a very “2018” style mono-metal throw would be the SF Cadence. There’s a pretty big reason SF’s yo-yos have dominated the competitive scene… They’re very well designed for today’s style of yo-yo play. Other notable designs that would keep with this mentality would be the SF Ceasefire, Smashing Float, YYF Edge and YYF Shutter WideAngle.
If you want to keep with the Organic design, the YYR Anomaly would probably be the closest to modern design. Mythril Flux would definitely fall along these lines as well but is quite a bit lighter than the Anomaly. Although lighter would be more in line with today’s style of play.
