Alright i will try to address some of your comments.
First i will attend to angles. I have not performed to a spectator but in front of a mirror the angles were good from the front around to the side. This is similar to the angles of a pass so i believe it could be performed live and it would still look good. (i would not have continued to practice the move if i was not able to perform it live)
I would also like to note that this is not an improvement on the clip shift. It is a variation. I am not trying to say that this method is the best but it is visually different. It is more open and it has a little more prestige to it rather than just shaking the deck with one hand. So yes it it defeats the purpose of the clip shift being a one handed covered move but that is why it is a "variation."
Now to answer jazzhands1 comment. Yes i did palm a card but it is the way i palmed it that is what i am showing. I used the clip shift to get it into an unconventional palm. Think about it when your overhand pulls away from a deck it usually curls into a loose fist. by palming the card using the clip shift i am able to do that. Thus my hand looks a lot more natural. Also this palm allows the color change to be performed quickly as the curled fingers project the card so there is less movement compared to throwing the card from a regular palm.
As for using it in a trick, you can use it anywhere you would use a clip shift.
The reason i like it is because it is a very natural way of bottom palming the card and the quick replacement, to me, makes a very believable color change.
