Golaloon Step by Step guide and OneHive tutorial video

Golaloon in my opinion is harder to pull off from execution perspective but it's a more powerful attacking method than GoHo.

There are a few things that can wreck your Golaloon raids if you don't take them into considerations:

1. AQ and CC : AQ is like another air defense. Deadly to your loons. CC can kill your raids really fast. 
2. Wiz Towers: the danger of wiz tower is that your loons will often clump together and one Wiz Tower can zap all of them away in a few seconds. 
3. You can't take on a base with 4  lvl 7 ADs all alive. You must manage to kill at least one of the 4. 

Scouting:

1. You want to look for a base with easier accessible ADs. If they are on the outter edge and far apart from each other, bingo you got a good base to work with. If they are all centrally located, it could work pretty well too but you must know how to time loons and lavas so your lavas don't hang out by themselves for too long. 
2. Can your kill squad kill AQ, CC and one AD all together? If not, move on, find another map.

Planning your attack

1. Obviously, your kill squad's job is to eliminate AQ, CC and one or two ADs. Think about what's the most efficient way to get that job done. You might need to quake open the base up so your kill squad can get in there faster. 
2. Once that portion of the base is under fire by your kill squad, think about your direction of attack by your Laloon troops. You need to pick a direction, either counterclock or clockwise to release your Laloon troops. We will talk more about that in the execution section. but for now, you need to pick a direction. 

Execution

Laloon execution is much much harder than Hogging. This video goes into details about execution. I listed some most important aspects of the execution for your reference. 

1. Because Laloons are more powerful than your hogs and your kill squad doesn't have to cover as much ground as GoHo does, I usually use 2 golem kill squad to just target at AQ, CC and one AD. 
2. As your kill squad pushes in, don't wait too long to start your Laloon portion because loons can distract the defenses nearby and ease the fire on your kill squad. I will drop Laloon as soon as CC is down and one AD is dead
3. You must pick a direction and do surgical deployment. Mass dropping loons will NEVER work. One loon's attacking power is massive so you don't really need a lot per defense target. I usually drop just 1 for archer tower, 2 for WT and 1 for any ground defense. You also want to start dropping 2 lavas coming in from different angels to absorb all traps. Timing between Lava and loons matter also. You don't want your lavas to hang out there for too long since they are much faster than loons. 
4. So as you rotate through the map, you drop more loons right next to the defenses and drop last lava as the rest of the Laloon travel towards the last defense. rage as needed.
5. Do not let the loons clump together near WTs. That will get your loons killed really fast, hence why we must do surgical deployment. The loons tend to travel towards the nearest defense and sometimes all of them will do that, which causing them to clump together. You must have a plan to counter that scenario by taking out the defenses that will attract them to travel towards wrong directions. 

Troop Comps

I use the following troop comp as TH9

1 CC golem

1 golem 30

3 lavals 90 (sometimes you can get away with 2, but I use 3 for maps with lvl 7 ADs and if I can only take out 1 AD)

15 loons 75

6 wiz      24

1 archer  1

Spells: 1 jump 3 rage or 1 rage 4 haste, or 4 quake 2 rage or 1 rage 2 haste.. Depending on the map.
