shinwoo toss up.

hey guy’s i’m having a hard time with some shinwoo yoyo’s, i love their throws and i would like to stay within the shinwoo brand, so please don’t try to say to grab something else, i have plenty of YYJ’s AND YYF, and many others.

what are the ups and downs of the:
ZEN (rebuilt)
ZEN6
Grandyo
and
Dolphin.

if you have them tell me what your thoughts are. please and thanks so much in advance, these are really eating away at me. and i want to get 1 and hopefully that will put these urges to rest for a while.
