My 9 year old son rides a Ronix Vision 120, we just moved him up to the 5-8 bindings If your son is already at 5.5 then get the 5 to 8. I am partial to the Ronix kids boards, I think they have the best kids shape. My daughter rides the girls version the Ronix August and she loves it. Seems to be easy to learn on, yet progressive enough to advance. So my recommendation would be Ronix Vision with Ronix Divide boots 5 to 8.
Have fun!
