I don’t have any suggestions yet because you haven’t really given an amount of money you would like to spend. Also, is there a specific reason for those brands, as in would you be willing to get throws from different brands? If you answer these questions we will probably be able to help you out.
Money isn’t really an issue, but preferably somewhere between $40-$80 for now. And those are just what I’m used to, but I’m definitely willing to try something new!
The Onedrop Chik is fantastic, especially considering the price. Can’t comment on YYJs as I don’t own any.
String is all personal preference really, you might need to try a few types till you find one that you like best. I like YYSL Ammo myself, but something like Kitty/Fat Kitty is cheaper so that might be worth trying first.
Bearing wise, it’s all the same really. Koncaves/Buddha Ripples/Trifectas are what I use myself.
I believe the last yoyo you mentioned is a Dark Magic 2? Only YYJ I can think of with a 2 lol.
I would grab a Burnside, a Go Big, kitty string, and some General-Yo AIGR bearings.
