According to the current rules the only cage we can't skip is bowsers. I have been practicing for 8 star and found many improvements, 2 of which being a much more consistent cage skip for w3 and w5, around 70-90% success rate and it's only been a day since I found them so this is with virtually no practice at all.

Are there stars that would be faster if we could skip w3 and w5 cages?
