Base designs and raid layouts

What is a good base design for Town hall 6 and what is a good army composition for raids? I usually use 60 archers 60 barbarians 5 wall breakers and rest goblins. Also what should I upgrade now that I have a level 4 laboratory? My lightning spells are lvl 2. Should I upgrade those?Attachment 13745

hello anyone here?

Upgrade the troops you use the most.I just recently upgraded from TH6 to TH7 and I was just using goblins on collectors. Not sure about a good base design I'm still trying to get one.
