By some of the comments I have read. Would you consider a line lock illegal. It operates with electronics. NHRA doesn't. Play back tachs. NHRA doesn't Just curious. And how much advantage are you really gaining with a solenoid. You still have to cut a light. You still have to shift right. Your car still has to be consistent. Whether you use your foot or a solenoid to hold rpm at the line. BIG DEAL. You still have so many other variables to contend with. And I even haven't talked about the biggest variable the WEATHER!
