Voltage Viper Challenge is a 2-lapper designed to be of technical difficulty - with many hairpins to brakedrift through and ledges to triangle dash off, racers who practice enough to get an edge on these harsh sections will be capable of taking the lead.
TIPS AND TRICKS
After the first turn, you can either go in the middle, take the stairs for ringboxes and go down them, or even triangle dash off the stairs after the first half of them..
On the note of triangle dash, you can use a raw one on that big ledge, or hold one and use it after a fastfall bounce.
The two hairpins afterwards will require you to use the brakedrifting at the right time if you are playing with heavyweights.
The multiple slopes after the big upwards jump are for, you guessed it, triangle dashing - but there are plenty of rings on their surface if you decide to fastfall over them instead. Make sure to use those in any case...and if you happen to get hit and slide down them for some reason, they have springs at the bottom for emergencies.
