Been trying various methods to collect custom items. Here’s the data I have so far, will update as I research more.

 See here for a list of all the collectibles in the game (Japanese and English)

So angry about this run. Look at it!

*For Classic, the amount you receive on the roulette affects the next roulette. So while these are “missed”, they potentially would have negatively affected the total number collected.

**I was awarded the same new move twice.

Also, I always went to the most difficult path on Classic.

Home Run Contest: 5 Minutes (Was following a method found on a Japanese blog)

Collected:2

Missed 3 (over shot by a meter or two).

Smash Bomb: 5:22

Collected: 4  NEW MOVE

Missed: 2

Smash Bomb: 5:22

Collected: 5

The good thing about clearing Classic is that it gives you a ton of coins, which can be useful for Trophy Rush.

Please note I have 6 more customs to find, so my data may be skewed.

For All-Star you are awarded the number of customs depending on your difficult level. 1 for Easy, 2 for normal and 3 for difficult. It doesn’t seem farming friendly at all.

EDIT, Monday 14:36: I have all the custom moves. Now I just need the hats. Runs not aiming for any custom moves will be added later.

I think Trophy Rush, 2 minutes is the most efficient way to farm right now.
