C.Falcon is a character which is only for selected individuals or better said 'born for it', are capable to escalate with him, your senses, especially reflexes must be really high evolved just well connected with each other and be mainly obtained by talent in hand with common and uncommon practice, so that you really exploit his optimal speed capability in advantage, optimally syncronising positioning timings much earlier, grab timings and knee timings, the connection with C.Falcon must be really high, otherwise I recommend anyone to give him up as one choice for professional purposes.
Wizzrobe is a perfect example, he doesn't possess a comparable tech like WestBallz, S2J, DruggedFox, Mango and many other top professional players, but his high developed senses provides him most times asserted predictions for his neutral openings, superior tactical positionings in all means, Wizzrobe assimilates the opposite information so well and fast, that he always finds an opening to break anyone's defense down without letting them fix it before, optimally synchronizing every movement according to the enemy's movements to still combine them after the first contact while keeping up with C.Falcon's insane speed, that all requires not only common and uncommon experience and practice, it can be only unleashed by talent.
AAAAAA
I would recommend you to start with Falco, not because he's easy, I believe that you're strong in a mixed way of an offense and defense term, I'm certainly sure that your type is mainly hybrid, after falling with Fox as your ex-main and finally Falcon as well, both characters requires a developed offense with the mere difference that C.Falcon requires a more special/deep connection than Fox, so rethink it and don't lose your time.
After you domain Falco, start with Marth as an option against floaties, follow PPMD example and develop your way to the top, wishing you much luck.
