LVTT is Lightning Volute Two Technique. That's what I call the ability to get two laps at the same time by crossing an air goal and then the ground goal. It works on Lightning Volute 2 and the Mute City Expansion Parks. LVTT is banned because a second lap is registered without having to go around the track.
I didn't know times set while going backwards are banned. Of course, not the entire lap is done backwards (the goal still has to be crossed while going forwards). Incase you don't know, some other strats I've come up with in Climax involve going backwards for periods of time. Such as Port Town Great Wings. Both RichardTaro and myself have submitted times using that strat. Here is the video of that:

How much backwards counts as a backwards lap? My copernicut for Big Blue Twin Course requires a little going backwards:

RichardTaro and Westu have both used that strat.
