What I look for in ignition systems, traditional system and instant ignition. I do not like any lag time to much can happen down range. I once had two kids on a motor bike (who were trespassing) ride in front of my half scale Napoleon. They paid no attention to our efforts to wave them off. Back then I was using firecracker fuse which takes forever. Fortunately we hadn't started the ignition process. Since then I have used linstock & quills, friction primers, or 22 blanks for ignition.
