I'm amending my answer. I would do hogs then pekka.
ten days left to max everything and ten days for TH9 upgrade. You can do both of those upgrades in about that time and be ready to upgrade lab once you hit TH9. You can do Golem upgrades at TH9. Esp since you maxed BK for TH8.
Waiting for 78 days to upgrade all that when you could be getting started on AQ, xbows, new defenses just doesn't seem worth it to me.
You will need some upgrades to do at TH10 when you are maxed and the game slows down with upgrades. save the gobs and healer for then haha
