Let him fly through EPGY. You could also skip him .5 grade ahead once in awhile (per EPGY recommendation, if he is getting > 80% correct consistently). DS slowed down in EPGY Algebra (8), at which point (without finishing EPGY Algebra) he switched to AOPS Prealgebra (textbook+solution manual only, self-paced), and AOPS Algebra 1 class after that.
