Sunset Trajectory’s(if can find) and Yomega Raiders are good for starting.
I’m not sure on SOS since I’ve never owned/played with Loop720.
Loop900’s are super hard to find as of now, YYF’s Patrick Mitchell (received email earlier today) stated there’s a possible restock on Loop900’s in late January, date not decided just a possibility.
Oh, that is weird. If YoyoJam does that, then it would not have a proper looping yoyo in production… Anyway, in that case, I would recommend the Duncan Speed Beetle. I heard many good reviews on it.
