I think what made the 07 different was the material. iirc, they moved to the 7071 aluminum starting in 08. I remember the yoyo just felt harder in the hand. I could do a blindfolded throw and tell an 07 from an 08 with 100% certainty. While a ti 888 does give me a big ol chubby, It would most definitely have that same harder in the hand feeling. At least thats how id expect it.
I’ve tried 07 - 888x (took a hiatus during the rest) my 07 is my favorite by far. Something about it. I can’t really tell you why either. Just feels great, and looks great (got a blue and purple higby)
