Uhh....So we should not advice him against something if it's a bad idea? Advising someone what they can or can't have is a GOOD thing, especially for someone new in the hobby.
Bad ieda or not we dont controle him. If he dose his home work hill know right from wrong, you also never lean if you dont try it. like a kid wont lean to ride a bike if hes worryed about falling. Ive had alot of "Bad Ideas" go good!
