.400 pro tree help

This is not something I heard, all I run is a pro tree. I have seen it on video and have made adjustments to my reaction times by changing which bulb I look at. I understand that led bulbs "light" much faster which would reduce the lag time, but honestly I don't think the tracks I run at have LED Amber bulbs. Not national events Atco/Cecil county/New England/Lebanon Valley/Englshtown/Island ect. It also comes down to how the tree is wired and how the controller works. Each track is a little different. I run at 4-5 tracks a year and qualify three times, if my reaction times are really to close for comfort I focus on the bottom bulb. I have noticed my RT were crap during qualifying and catch myself looking at the bottom bulb.
