I've some questions regarding equipment effects...

[Unowninator]

1. Does Anchor Jump (×1.4 falling Speed) affect knockback in any way at all?
2. Do the added bonuses from Desperate Specialist/Unharmed Speed Demon vanish when they wear off? Or do they just simply stop increasing?
3. For some reason, I can still be stunned & knocked back with the No-Flinch Smasher. WTF?
4. I'm not noticing a difference with Crash Lander. What exactly triggers it?
5. Does Item Pitcher/Hurler/Lobber effect specials like Bonus Fruit, Metal Blade, or Egg Throw?
6. Is Trade-off Defender (Start the match with 30% damage, but take only 0.8× damage from attacks) worth it?
7. How does the All-Around Trade off Work? And does it reset when you lose a life?

I don't really know about the other questions but trade off defender isn't really worth it when you already start with 30%... it's kinda stupid. I can understand the offense and speed boosts but the damage directly counters your def. buff.

For question 3, the description says that you won't be launched by standard attacks while charging a smash attack. This probably means that only the standard attack, f-tilt, u-tilt, and d-tilt are affected, while all the other attacks can pierce through the flinch immunity.

I haven't tested this though.
