JS for guards trains everyone regardless of height faster at JS than JS for forwards.
Are you sure??? Well I'Ve looked at the training speed thread and saw that JS for guards, wingmen and forwards are all 2-3 weeks. But the difference is that training JS for forwards trains many other skills too, compared to training JS for guards, which only trains a few other skills. Maybe JS training for guards is quicker because it has less chance of other skills popping up?
