My brother throws one hell of a show! He plans it out months in advance when he does puts in a dealer order for himself and a few select customers. Fills up a 35 ft enclosed trailer every year with cases of fireworks. Takes us a few hours to wire it all up and lay it all out for a computer controlled show. Think we used something around 90-100 ignitors and 60-80 ft of fuse this year for the ones that are all fused together. The finale was 144 shots all within 30-45 seconds. Pretty well rivals most small town shows.
