Thank you UnitySharp for your great guide!! Really is refreshing to see something different. Even better how you have all the stats to prove it, not like some others here who can 3-star any base and resist any attack without any proof...

I also noticed how some of the haters disappeared after the guide got some meat to it. Anyway....
Also thanks to Fhou for your contribution to the TH8 world, I find myself in a very similar situation to you, 76% done with skull walls and only 2x archer towers left to start upgrading. BK is maxed out and I still have enough time to just drill myself to an AQ when I hit TH9 29 July.
Anyway, I'm here to ask for advice, as this has now changed my upgrade strategy... If you don't mind looking at my TH8 upgrade thread in my signature, you will see my Minions lvl4 finish today, in 2.5 hours actually, needing to start PEKKA lvl2. My healers are still lvl2 though, so I only pegged them for an upgrade sometime during TH9. With this new strategy, it would seem I should rather start my healer research to lvl3?
Also, you will notice a lot of downtime on both my dark barracks at once, basically because I never use dark troops. Would you say I should blow off upgrading one of them and just take one to lvl4?
Then final word :- This guide has found a special spot on our clan website, hope you guys don't mind!
