Radius / Profile change for kids

[noupf 42]

Hey all, I know we have some profiling gurus on here and I am trying to help my son who just turned 8.  He's been skating for a couple years now and plays on a local AA travel team.  His skating ability is good and is on par ( not phenomenal ) compared to his teammates, but he looks stuck in the mud when he needs to get up and go during games.  He's very tall for his age and solid ( about 85-90 lbs ).  I have him on 5/8th regular hollow and he's currently in a size 1.5 Bauer Supreme M4 Junior skates that has removable steel.  The steel is the Bauer 13' radius "balance blades" and he's been on those 13' radius blades since he started skating a few years back.  I grabbed his next pair of supremes on clearance ( also Bauer Supreme M4's ) in size 2 and they too have the 13" balance blades and the same length steel.  My question is, should i get him out of the 13" radius and if so, what radius would be ok for him to transition too?  Or do i explore the profiling route?

I do know quite a bit about profiling for adult size skates and how it works and the potential benefits ( i'm using an ellipse profile on my CCM 100k Pro skates and loved it from day 1 ), but i know little with regards to kids size stee bc the steel is so short.  is there a benefit or specific route to go for kids sizes?  Runner length is 212mm

Thanks !!
