The only advantage of the top bulb racing is the easier consistency, because of reacting to the first lamp that lights, but I'm going to tell you all something......I've watched over 30,000 elimination rounds happen on the timing system, and there are as many .050, .060, .070 and even worse R/T's thrown out during the S/P class as the Pro class.
The average winning package (total of R/T + off dial) between S/P and Pro class difference is only about .015......you'll squeak through a lot Pro class rounds with .030 packages, you need to stay .020 or better in S/P to do some damage. But again, the incidence of a .030 or .040 package taking the win lamp in S/P happens more than you'd think.
William Hamilton from Cincy took the runner up at the 2004 Million Dollar race with no rounds of the 9 that a .040 package would NOT have beat him, he was .097 on the tree in the final round, his opponent was .023. That earned him about $100K for the day. His best R/T of the day was a .041, ANYONE with a .020 light, and .020 off the dial in would have taken him out right there.
Most common and worst mistake is trying to go .00x on the tree all the time.....take 'em when you get 'em, but they scare me to death. I set up for an .008 to .012 tree, since I know my normal human variance is about .007 plus or minus (net .014 range) if I "screw up" early I'll be .001, if I screw up late, I'll still be .019 and still have a chance to win. (especially if I carry .02 or .03 in the bag on the dial)
Driving the stripe is another whole subject.
With a good car and a green light, lots of good things can happen, when you red light you just gave it away, the only way you can win is if the other guy crashes or crosses the center line.
The key is to try to lay down what you've decided is your acceptable package, and hope you don't get in the way of the guy that throws down his .00x package...when you do, you shake his hand and try again next week, but go home knowing you were in it.
Truthfully, .00x packages are pretty much a lot of luck, dude our master timing clock measures out to the MILLIONTH, and we're all human. NOBODY lays down more than 3 or 4 really good packages on their best day ever, it's all about what happens on the other side.
I've been sent home twice in the same day with packages of .005 and .011 on my side.....what are ya gonna do when that happens?
I just shake my head and say, dayaammmm, I was just in his way.
Anyway, to answer your question, there are many racers out there footbraking in the big dawg classes, and doing as well as the next guy.
You always have exceptions in any sport......Scotty and Edmond Richardson, Jason Lynch, Luke Bogacki, Troy Williams, Ken Underwood, etc., etc...... but their key is the amount of seat time they get.
ALL of those guys will blister you just as bad in a footbrake door car as in their S/P dragsters, if they hit it just right, but they all get beat just as regular as the rest of the world too. They win events because they might have 2, 3, 4, or more cars entered to start.
It also means they got beat 3, 4, 5, times that day too.
It helps to keep it fun, regardless.
