I'm on a mission to fill in my Sphere Grid completely, and was wondering, is it actually possible to get 255 stats for everything? If not, I want to know the best stats I can get to 255 before I run out of space on the Grid. Also, I don't mind on getting 99,999HP, but I do plan on deleting all the HP spheres, and replacing them with +300 so I can get to around 40,000 - 50,000HP...

Anyway, help will be appreciated.
