Notes on that exact DT canon setup:
If you look ahead far enough you often can know if a PC works or not before you place the 3rd O
Because if you place it at the right side first you can get alot more PC-able sequences
But if you know you can't PC with the sequence you can put the O on the left and transition like this (amemiya also does this):
which will always work like that if you get the L before S and T after you fired of the DT canon.
And to add another opening to your list, TKI variation into PC:
All those fumens are taken from one of Squirtles opponents in PPT who tried to beat his center 4 wide with that
He got that PC ALOT when he could get that first opening T spin (and without hesitation too)
(unfortunately Squirtle deleted all his VODs

so I don't know what that players name was)
and some more:

(im too lazy to combine them all in one)
And the nice thing is: if he knows he can't do the PC with his sequence he can just do the 2nd TSD instead like one normally would do.
