• Have your back against the wall
• Align yourself so see the whole pink building
• Aim at the top of the electric box
• Run and throw just before you hit the wall, more speed is better

Works best if you have this smoke already up so you won't be spotted from the connector.

Warning: Throwing this nade might result in getting sprayed trough smoke. I take no responsibility of any such event, please use your in-game voice chat to show your frustration.
