ok well think you darykjozef...i trust you because you are in a higher division then i am so you have been playing longer...ive just heard that from many people.
Whether or not I'm in a higher division is irrelevant (ask anyone in my series, I'm famously retarded when it comes right down to it).
I think the reason most people say to train the skills that take longer (OD, ID, JR) first is because training a 25-26yo in these skills becomes thanklessly slow when compared to the faster skills (JS, DR, HN, RB). In actuality, the slowdown is the same on all training, but e.g. 5 weeks for a pop in JS feels better than 8 weeks for a pop in OD (these numbers are random just to make a point).
