Thank you for your knowledge Varist. I will stick with the thumb grip, and maybe invest my time into something else. I just wanted to try it because I see falcos double/triple shining on a shield into a full hop all the way to the top platform, then can drop into a dair or whatever from there.
I am relatively new, and am still practising shffling,waveshining and wavelanding but I do enjoy looking for new ways to step my game up
keep it up brah. Once you know the waveshine timing and you get the idea behind wavelanding (you don't even really need to know how to do it for this) I would go for shine wavelands.
#1 tech skill to practice would be shine wavelanding onto platforms from below. Getting that consistent revolutionizes how far you can extend your combos against fast fallers and it's criminal that we don't emphasize how important that tech is to new Falcos.
Get a level 3 or 1 Fox or whatever you want and pick Battlefield. Make him walk toward you until you and him are both below one of the side platforms. Shine him so that he lands on the platform above you. That's the position you want to keep recreating: you below him, him standing on the platform.
Full hop, but you have to be fast because while you're accelerating up towards him, be already holding down on your analog stick. Press B to activate shine when your body is below the platform but your head is poking through the top. Your shine should connect with the Fox. As soon as the hitbox touches the Fox through the floor, press y to use your double jump. Remember that you're still holding down on the analog stick. Literally immediately after you press Y for your DJ press whatever trigger button you airdodge with so that you waveland directly down onto the platform.
That all takes like half a second and it puts you into position to do a dair or an uptilt or whatever you want to pillar with. Just get consistent at that and your Falco will automatically become legit and you can actually start learning combo stuff instead of just wasting time jumping around trying to get rising dairs to hit people or whatever it is new falcos do on platform stages.
