What Bonuses on a Focus Would Fetch the Most Money?

So which bonuses on a focus do you think would fetch the most money? It doesn't matter if it's PvP or PvE, just one that would be worth the most and worth collecting (hint hint :P). Any suggestions would be appreciated :-)

20/20
10/10
30 +5

some of those

So which one do you think would be the best to collect? *cough*

there all as rare. any ?

good luck if u want them tbh

Which one do you guys think would go best with a 5>50 10% recharge wand for PvP play?
