i think the bunting thing can actually work ive gotten alot of singles messing around doing that using items to hit the pitcher before they can get the ball
wii u has a advantage but i still recommend running the game u can get a really good time on wii if it were up to me id split the leaderboard to wii u and wii but not mod tho.
from what i understand yea wii u has faster loading times so overall its faster to run on wii u lmk if you have any more questions good to see people interested in running the game
