You should've 1v1F until DR/HA 12-13 to get his elastics setup. In my opinion, I would've did 1v1F until his DR/HA is 12-13 then pound ID to 13, IS to 13 then alternate IS/ID until both reach 16 then JS/G to 12-13 since I like my bigs to have good JS.
You should continue training ID until it reach to about 14-15 then train IS until 15-16.
