holy priest gemmingFollow

i had socketed my gear awhile back and just went with the flow with what i thought would work good, but i would like to hear what the professionals have to say. i currently have all my blue/red sockets filled with 12SP/10spirit and all my yellow sockets filled with 10spirit/10int gems, was wondering if i should be socketing differently. im usually top of healing meter and bottom of overhealz in raids. thanks http://www.wowarmory.com/character-sheet.xml?r=Lethon&n=Vadius
