I have found a very good way to farm at Town Hall 8
Yesterday, I was playing around with farming comps, and I found one that could easily hit unprotected storages and collectors. This is commonly known as BAM. I used it for a bit yesterday, and got 10 skulls done, with no boosts or no long hours of playing. I farmed at around the 1600-1650 range. I used 2 rax orchers, and 1 rax barbarians, and this is because one of my barracks war upgrading to level 10. I also only had 1 dark rax minions. I found that this leaves a very good balance of barbarians to use a meat shield, and archers to do the damage. This also leaves a few minions, to get unprotected storages and to get a few more collectors if needed.
I will upload a video soon,
