I'm no training guru, but maybe you could start with DR for forwards to get up DR and HA quickly, so the other skills train faster with the elastic effect. Then depending on your chances in the league and the rest of your team, train them either at a spot that makes you weak (if you don't have a good chance anyway), or at a spot that doesn't make you much weaker (if you have a bad PG, training your trianees at PG isn't gonna hurt you as much), if you want to keep competing.
I'd save JS for wingmen for when you want to compete, because it gets pops from other training as well, and you can play them at their natural position thus keeping your team balance/strength intact.
