As Exiliado said, experiment. Classical is neither here nor there and base building is for experience, not saving rss.
Having said that, think of your base as a maze. Don't give your enemy a straight line to anything. Place your buildings or wall squares off-set from each other. Make troops meander and waste time walking around corners, since troops will take the easy path before trying to break through walls. Place your defensive structures and traps accordingly.
You won't have many of them but traps also work well in groups to slow the enemy, creating bottlenecks, while your towers do the shooting. eg: caltrops with ambush traps. If possible, place ambush traps in front of defender buildings so they create bigger bottlenecks.
