First of all, I made the same topic on French forum
here. My English's level isn't sufficiently good to do a correct translation, so I just say the main things (and maybe someone will be able to do the translation after

) :
Pipehit is forbidden on non-NBT site, but nothing is written on NBT site ! It's a technique, where you can hit a pipe and cross the sand without losing speed. A lot of players had to see that at MC4's last corner for example. My
1'15"93 non-NBT at MC2 contains a pipehit at 4th lap. If you don't win time and if it's involuntary, we can accept it. But Krysster (Christophe on the site) has the idea to do voluntary pipehits. His example is at MC1. He wants to build a boost after 1st corner, do a pipehit at 2nd corner, then cut a lot of sand with pipehit's effect and finally launch the boost after pipehit's effect (as a slideboost, where the boost starts after the end of slide's effect)... We still don't know if we really can win time with this strat, but I think it's possible !
So I create this topic to have your opinion ! There is nothing to say about this strat, or do we have to forbid it, to still keep some pure driving for Time Trial ? Of course, if we forbid it, it can always be added on trick/glitch WRs...
IMO, I'm against this strat, cos it removes some pure driving spirit... It's almost like a glitch. Or like breaking blocks on GVs to do faster flaps...
