I have been using all max dragons with great success to 2-3 star th10-11 bases. The trick is to look for bases where some of the air defences are near the outside so they are gettable right off the bat. Here is one of my recent 3 star war attacks. Granted this base was rushed but it works great on non rushed bases as well. I get 2-3 stars almost every time. I highly recommend all max dragons.
