[STRATEGY] Need help with Builder Hall Strategy

I have been stuck at 3600 trophies for ever. BH8 Double Cannons at lvl6, Cannons at lvl6, Giant Canon lvl7, Archer Towers lvl7, Firecrackers lvl7, Crushers lvl7, Hidden Tesla 2 lvl7, 1 lvl6, Roaster lvl6, Mega Tesla lvl2, Multi Mortar lvl7, Mines lvl8, Mega Mines lvl8, Push Traps lvl8, Spring Traps lvl4, Guard Post lvl6, Gold Mines lvl8, Elixir Collectors lvl8, Gem Mine lvl6, Elixir Storage lvl8, Gold Storage lvl8, Clock Tower lvl7, Laboratory lvl8, Builder Barracks lvl 10, 3 walls at lvl4, rest at lvl5

Battle Machine lvl16, Barbarians lvl14, Archers lvl14, Giants lvl14, Minions lvl16, Bombers lvl12, Dragons lvl12, Cannons lvl12, Witches lvl15, Balloons lvl14, Peka lvl4

I have been using balloons and minions or all witches. 1 out of 5 attacks is a low percentage 2 star, the rest are 50-70% 1 Star attacks. Have tried giants\barbs\cannons with very minimal results. Same with bomber\barbs\Peka. I am sure I need work on attack strategy. Hence the post.

I am predominately matched with maxed bases (minus walls), maxed troops and maxed battle machine. Last few attacks are as follows.

*68% => *70% loss, **53% draw, *53% => *68% loss, *53% => ***100% loss, **61% => **53% win, *59% => *55% win, *59% => *70% loss, 35% => ***100% loss, 48% => 40% win, 48% => *48% loss

Let me know your thoughts on upgrading, attack strategy, base layout.
