[Agent Buckshot Moose]

All depends on the map, where the flag is, and how fast enemies can get to it. If enemies are coming in slowly, more pipes. If enemies are coming in faster, less pipes. I will usually lay 2 or 3 around the flag and then spread out more around it. Larger radius helps compensate for reaction time and also some attackers don't seem to notice when your pipes are spread further out.

Offensive demo: very good at punching holes in enemy defense assuming you don't blow your teammates up. Not so good at movement unless you want to take out half of your health, which can be inadvisable since you don't have much to begin with. Offensive demoman works best on smaller maps where a lack of concs won't hurt as much. Also smaller maps usually = smaller rooms which makes the demoman that much better.
