D-Air spike to Footstool

[!Boom!]

Easy to pull off right? But I don't see a lot of videos that show off this move. Does anyone usually pull off this move successfully (since I find it hard to make contact with the opponent with the d-air)? I especially find it hard to d-air spike:

Falco's OverB
Fox's OverB
Mario's Cape recovery
Lucas/Ness Recovery
Metaknight/Pit gliding recovery
Pikachu's recovery

I have no problems with the heavy characters. So does anyone have any tips to make contact with these or any characters? Thank You.

I find this hard to do because most of the people I fight have really good DI.

If I go for this most of the time, I'll be the one getting footstooled. It can work against people who don't know about it, though.

It is really hard to Dair a phantasm (spacey over b) so i usually just Nair so they run into it, or if I feel like being a risktaker I'll Fair spike which sometimes works.
Mario's cape=annoying as crap. nuff said.
Lucas/ness's recovery, you just want to hit the pkt ball.
and pikachu's or luigi's over B recoveries=easy Fair spikes!!!
