This is a similar thread for those who missed it:
I am somewhat of a collector, but have just begun really. If I really like the yo-yo, I want one to play, one to keep mint as a collector. To answer your question:
4 MMN, one to keep mint, one to beat up, but I have a nickel and a sodablast, so with that logic it equals 4.
3 Di Base, I had a purple polished, but I had an opportunity to buy other colors I preferred in bead blast, a finish I preferred, so I got a blue and a black. Color variety is cool. I play the black one, the purple has damage, the blue will be mint.
3 YYF Genesis, I bought a YYE Edition but wanted to keep it mint, I collect those, I wanted one to play with so I got a small bearing Genesis, until I realized that is rare, so I can’t play that one either really, so I just bought a 2012 Edition to beat up. They are all different versions of the same yo-yo.
7 Dingos, I just made it my goal to collect the entire rainbow of colors, when I see them, I buy them. I have a half black/half blue that I beat up, I don’t play the other ones.
2 Cosmos, they are just pretty, I don’t throw them around, but they’re nice looking so I found two different colors I liked over time. Color variety mainly.
3 Dark Magic II I have a beater one, a signed one, and a YYE Special Edition collector one.
2 YYF Catalysts, Harold Owens Edition, both versions. I play the gold with blue splash and keep the other mint.
2 Spin Dynamics Monkey Fists, the mirror silver to beat up the soda blast nickel to keep mint.
2 Exit 8s, a black to beat up, and a blue as a collector.
2 General Yo Entheos, a gold to play, a blue/green as a collector
2 General Yo ministars, one to play, one to keep mint
2 Spyy Supras, one to play, the other to keep mint
2 Burnsides…you get the gist
2 Dietz…same idea
2 Popstars…got one in a trade and already had one, just ended up with 2
2 Yoyojam Classics, I had one, and got one in another color as a gift.
There are more, but those came to mind.
