This is an idea which popped into my head in another thread but mathematically it seems to work out quite neatly.
One of the problems in game for humans is metas always have larger dice pools (attribute + skill). This is largely because the 'bundled' attribute costs of metas is lower and that's without even considering their higher attribute caps which come with them. Generally I don't feel +1 edge makes up for it.
The idea is rather simple... Reduce skill costs by 25% for humans. This means more and more varied skills at chargen. And lower advancement costs to the caps.
If you then proceed to remove the rank6 skill cap. It has the added benefit of giving mundanes unlimited advancement in the same way that magical/technos do and giving humans a slight edge there. (the positive quality which allows a rank7 skill could easily be reworked as pig a 'tag' skill then that one gets an equivalent cost reduction). Generally the problem w/ street sams and hackers is they run out of things to spend karma on and eventually run out of essence... this addresses that problem.
