Well, if I were to use the Koopa Clown + Roller + Super Glider combo, I'd get good sea control, good air speed, average air handling, and a strong mini-turbo. The small acceleration hindrance that the Koopa Clown offers is negated, thanks to the Roller tires' acceleration boost.
The main flaw with this combo, however, would be the low speed, low weight, and low off-road stats. Drifting would also be hindered if I used a Light class character.
Alternatively, I could swap the Super Glider with the Paraglider (or Swooper) to max out the mini-turbo, but the air speed will drop to boost air handling.
On a different note, my PHP script now includes the hidden stats.
