I believe that Pein suffered from PIS when he sent Itachi and Kisame to be the 30% clones to delay team Kakashi and Gai. Allow me to explain.
I can understand why he sent Kisame due to his huge chakra, but sending Itachi without enough chakra to use any of his MS jutsu was silly. Don't get me wrong, Itachi is still a great ninja without his MS but he is hardly as good as other worthy substitutes from Akatsuki
Hidan
Hidan would have been the perfect choice to delay the enemy, the man cannot be killed. It would definately take the teams a long time to figure out his secret and someone would have died to get to that information from Hidans ritual. Furthermore, 30% chakra is hardly a handicap for Hidan since he doesn't use ninjutsu and really doesn't use much chakra to fight at all.
Deidera
Deidera is also a great choice for the 30% clone. He can blow himself up without any consequences since it isn't his real body, much like the exploding bunshin he used against Team Gai. I don't think it would use 30% of his chakra either after having seen the amount of large explosions he used agaisnt Sasuke.
Summoning Pein
Summoning Pein would be a good choice as he could just summon the rest of the Pein bodies from the rain village. And when he does that you then get a full 100% Pein.
So Pein must have suffered from PIS to prevent him showing off any funky new Akatsuki and so chose some illogical choises.
