Games : feedering account research

so i made this feeder account for my main coc account. i got level 5 wizards a few weeks back and have been pondering where to go. i know for defense that dragons and wizards are the most logical, but im starting to think about what troops i should be researching for later purposes. mainly thinking about farming, as its nice to have that turbo button when you come across those 600k loot raids with 2k de up for grabs! also to clarify this is strictly for farming and wars and watnot, i know dragons and wizards are the most logical troops to use defensively, and arguably the golem and witchs (im not 100% sure of the golem but i can see it being good).

If you have suggestions please let me know, here are my thoughts.

1) getting balloons to six is important, level six balloons are monsters and are very useful in lots of different comps. 2) getting dragons higher up would be good, especially since i can do so without going to th9 and they are such good troops for both defense and offense 3) pekkas seem like they might be good, but they are even more expensive then dragons and i dont know if its worth it. need to try it a few times 4) giants, im not sure where they would fit, seem like a cheap alternative, but level 6 giants are really strong. 5)if i get my main to th9 then i will be able to hold 2 level 4 healers which will help alot with farming especially if im using giants wallbreakers goblins and some archers.

for DE troops im curios how hogriders would be, they arnt to expensive (in comparison to other troops) for attacks. only problem is researching them up is brutally time consuming and expensive. i dont know how effective a golem would be, but it could be good. and finally at th8 i can hold 2 witches, and they only need to be researched once to cap their levels. I have no idea how effective they are though.

keep in mind this is a FEEDER account, so cost and build time arnt as limiting. if lvl 3 pekkas are 10x better then lvl 3 dragons for just having an overload button while farming for when u get those 600k raids, then the costs dont matter at all. the only cost id consider is the witch, which costs 700 DE at level 2, which is kinda alot imo, but im not sure how effective pumps are at th9. anyway let me know what you guys think!
