Let’s have a drag strip Christmas tree discussion

Technically what I do isn’t a Pro tree but we (box racers) are leaving off the top bulb which is what pro tree racers do. Our delay box does the rest.
Delay boxes are the competitive way to go. Especially with consistency. The only downside? Looking foolish if you mess the setup. Lol. Its not as common. But when they first were making the norm? I would see at least one a day sit there. Then take off a second late.
