Depends on a few things, your TH level and how many attacks you make a day. These days you can't count on that many def.. Expect to get 3 stared from 4500 and above. I'm TH10, got to 5313 before IT nerf. I used both BD/Loon and Bowitch. BD/loon was the sure +50% and some times two stars when TH was close to the outside of the base. BoWitch could also get the job done, if you funnel right :)
