Ok so I my son is 9 and currently riding a Burton Chopper with Custom Smalls bindings. He is in a size 6 boot this year so he will need new bindings next year as I'm sure his feet will grow. My plan was to pick up gear for him (new board and bindings) when they go on closeout at the end of this season and I was looking at the Union DLX bindings as the M/L size is supposed to fit from 7-10 which means he could use them for a couple of seasons unless he goes nuts with growth. I know they are at the low end of the Union line but I'm thinking since he is young and light they should be just fine. Can anyone give some real world feedback on their quality?
