FYI, I use the Crusaders. (S M M M L)
I understand that there's (mainly) no such thing as a 'best Build' for each of the sports; it's 100% playstyle-based. A lot would probably use a team with SMALL characters (Speed Strikers, especially) but for Kart Racing and Supercross, LARGEs seems to have higher max speed at the cost of low acceleration (handling is the same). However, due to needing to brake on some turns, the 'higher max speed' benefit becomes almost nullified. Same applies to Snowboard Cross; however, LARGEs seem to accelerate faster at the very start for some reason, so I usually pick a LARGE for that sport.
Additionally, I'm unsure if some sports (ex. Archery) even have a difference between Builds (but maybe that's just me).
If possible, could someone make a guide specifying what Builds are beneficial for specific aspects of each sport (pros/cons)?
[FYI a character’s “Build” is either S, M, or L (SMALL, MEDIUM, and LARGE, respectively).]
