cue
I would say buy him a regular cue and let him grow into it. I subjest a joss i woild also buy a rubber cue butt cover for the cue until he get taller. Also really work with him on his form. Now there are quite a few good 48 inch cue out there , but i think it better for him to use a 56 to 58 inch cue. I have a very good friend who went threw this lasr yeat and it work well with his 8 yr old, who is 9 now and play with a 58 in joss cue with a rubber butt cover witch i got for his sons cue.
