X-Treme is well, Extreme! This 165 shot, mixed shape, mixed bore compound lasts nearly 2 minutes. Starting strong with big Z-firing bursts of gold tails to gold brocade crowns with green glitter, W volleys of red and blue tails to coco. Volley after volley, shot after shot this firework really does impress. Usually cakes or compounds with mixed bores will start with the smallest and work their way up. This cake starts big, mixes it up in the middle and finishes with a lovely butterfly of comets and crackling.
