I would say giant healer is more TH6 but....
I stopped all that malarkey by getting air defence in, from day one and keep maxing it before each th upgrade and making it well deep and protected by cannons, arch tower and mortar inside my base and made sure they were always maxed before upgrading th to next level.
Whilst I was going through this game stage, Most people trying to attack with a giant healer combo didn't take care of taking out the air defence first before launching their healers behind the Giants and so the healers would be shot down quickly by air defence and towers and giants are taken out by cannons mortars and arch towers.
no need for another trap but another guys idea about upgrading spring traps was ACE !
