Attack Ring: Triangle Wing
Strong Upper Attack in left and right spin making it a competitive Traditional Upper Attack part, with slopes of equal length and angle in both directions meaning performance is identical in either direction.
Some Smash Attack from front of the slopes, and the heads, more than Upper Dragoon, however if you want a mix of upper and smash, Triple Tiger and Upper Claw are much better choices, being more Smash Focused (though Triple Tiger has too much recoil for Spin-Stealing Upper Attack). In Left Spin, however, Triangle Wing is the top choice for this criteria.
More recoil prone than Upper Dragoon which would be a downside for Spin Stealing Upper Attack, however the additional Smash Attack can come in handy against some opponents, meaning it is just as viable a choice and a competitive part for this type.
Defensively it is outclassed by Upper Dragoon due to the wider spaces, under-wing gaps and overall more angular design which collectively result in more recoil. As such, Triangle Wing isn't competitive for defense or survival types.
Overall, a good Attack Ring, and a nice variation on the popular Upper Dragoon, but generally not quite as reliable aside from in Right Spin Traditional Upper Attack.
