Well Xaviermace In hind sight now, looking back, id have not fully extended my reach, rather id have pushed the obstruction, backpedaled a bit while trying a bang so I could attempt to take cover if the call became compromised.
....but the factor of enemy taking a new position and getting a tactical advantage on me, I still think I may have took the shots. But I'm basing my opinion on the premise I don't know those players or how they might honor or react to such calls. Say if it were some local guys, id probably be more comfortable with an aim and bang. It's really a tough decision really. Trigger discipline is one of the more difficult habits to maintain when you cant predict the other players alittle.
