the g5… it is a pretty big yoyo (2.22" diameter) it is solid at 69 grams (it says that on the box) (yye got it wrong and said 65). huge rims make your finger fit in the perfectly! just as smooth as the 888. it can go fast when you want it to but i preffer not to. it makes your tricks just flow. a sleeper can go for an estimate of 10-12 minites with its supreme rim weight. only problem is it is super noisy with z-stacks but quiet when you take them off.
hoped this helped you
