I would say the Vinci is too big for the average 10 year old. It fits my 14 year old fine, but she has larger than average hands for a kid her size. My 10 year old said it felt too big for her.
Would love to find an Easton synergy 33" for my 10u DD. the mizuno GX 101 black with neon yellow writing is too small, and the GXS 92 is too big. Been looking at the new Easton synergy, light tan color-anyone know if its the same as the older black syergy?
