Star Alliance - Crediting SQ class N and E miles

Hi, I'm flying with Singapore Airlines in class N, and with Virgin Australia in class E. I'm not a very frequent flyer (and I try to stick with budget fares most of the time anyway), so I was wondering, to which FFP should I credit those miles? I saw that several of them don't accept them at all, but at least KrisFlyer does, albeit only 50%.
