Sorry, when I asked my question before, I think people misunderstood me. Totally my fault; I wasn't using the correct terminology. When I said CC'ed U-smash/grab, I meant Dash-canceled U-Smash/grab. That is, smashing down to cancel your dash and then smashing/grabbing.
I'm sorry for posting the same question again, but I'd really like to know the answer.
So, basically, I tend to do a dashing U-smash/grab two different ways:
Method A: Smash forward (dash) > Smash down (Dash-cancel) > C-Up/Z (U-Smash/Grab)
Method B: Smash forward (dash) > Smash up (Jump-cancel) > C-Up/Z (U-Smash/Grab)
Now, I'm sorry if I'm being a total noob, here., but, in an effort to better understand the game, I'm going to state my assumptions so you guys can tell me where I'm wrong, if I'm wrong:
1) There is no difference in the frame counts for a Dash-canceled U-Smash/grab and a Jump-canceled U-Smash/grab.
2) A Dash-canceled grab performs a standing grab, not a dashing grab (is that the correct term for for it?)
Logically, if both assumptions (1) and (2) are true, then it follows that Method A and Method B are, at least within the game, exactly the same. So, whether you use Method A or Method B is entirely a personal preference.
Sorry to go into so much detail, but one of my best friends who has adamantly refused to play SSB:M for the past three years has finally decided to learn to play. So, last night, I taught him a few of the basic techniques (I'm no smash pro, but I definitely do know more than him) and, when the concept of dash-grabbing and dash-smashing came up, I taught him both methods and he asked me if there was any difference between the two. I didn't know. So, I came to the only reliable source for accurate information on Melee techniques I've found, the Smash Forums.
Sorry for the long post, but I really don't want to give my friend any innaccurate information that might turn him away from the game.
Again, my question is: Are Methods A and B (stated above) the same? If not, which assumptions (1, 2 or both) are incorrect? Or is there something else that I'm missing completely?
Thanks again, guys.
