The best of my tracks revisited on the login:

-taf-


The names stay the same but with a "ult" for ultimate version

NS Powered ult ( a dubble left corner and a little jump remplaced by a 180° wallride, a little offroad and a loop)
Ridin' ult (the landed road changed by a platform and jump changed too)
High Speed Ring ult ( the high jump changed by a loop more fun and smooth)
O-Gravity2 (now totally full speed) jumps more smooth

to come:

Extrem ult
RoundCriZz ult
