i still think a rider shouldn't get excluded unles he actually touches the tapes ... if riders want to take a chance of anticipating them then thats up to him, as long as he doesn't touch them .. if someone gets a 'flyer' then good for him, and if someone is twitchy at the start and causes someone else to touch them, then thats gamesmanship.
as long as a rider doesn't touch the things, then it might get rid of all this crap about unsatisfactory start
