Here’s my thoughts:
I bought a Big You for the purposes of starting to learn off-string, and a Fiesta XX for actual off-string play. I’m a ways from wanting to venture into 4A, but the time will come. I want the stuff ready when I am. At under $23 each, these are proven performers and at fantastic prices. I mean, if the guy who designed the Fiesta XX is winning national titles with a $22.50 yoyo, well, that’s good enough for me.
I also recently picked up an Aquarius for super cheap on BST, which will also be used to learn 4A. Price was close to(with shipping) that paid for the Fiesta XX, but less. I won’t say how much less, that’s between myself and the seller.
However, my thoughts are to start cheap. You’re gonna beat this yoyo up from dropping and what not, so might as well start on the cheap side. I’m not going to recommend for or against the Griffin Wing, but the price tag makes it easier to not mind so much that it’s getting beat up, so there’s a valid consideration. But, to step up to better items, such as the Fiesta XX, I really wouldn’t spend more than that YET. Wait until you learn 4A and get some time into it, then upgrade to whatever you want. That’s what I’d do.
YYJ Equinox: $44.20
YYJ Fiesta XX: $22.50
YYJ Big Yo: $22.50
Shinwoo Griffin Wing: $15
You’re gonna beat it up to start with(not intentionally), so think low costs. If you like it, then spend more later when you get some skills in that style. Since I know I have a hard time grasping this stuff, the Big Yo just makes sense, plus I have other uses for it as well. But, if I was better, I’d have skipped the Big Yo entirely and just saved the money and only purchased the Fiesta XX. So, I’m suggesting you narrow your choices to the Fiesta XX or the Shinwoo Griffin. If you enjoy 4A, you can stick with whatever you purchase or get an Equinox or something else.
Oh, and practice over carpet or on the grass so the won’t roll so far away. This is a style best leaned outdoors on a soft surface or where there are high ceilings and soft floors if indoors.
