I like soft kicking at the 14 ball or the Ghost's soft roll of the 15-ball to the bottom rail. The soft roll on the 15 would depend on the scratch angle, like he said -- not shooting it if it looks like a scratch angle. Personally, I would not cut the 15 to make it -- it looks like too tough a shot for me to want to bet the game, although the camera does foreshorten the table quite a bit.
No way would I kick hard enough to skim off the 5-ball and go back up table, although I like that shot in other situations. The way I see that kick -- advocates are talking about hitting it basically like you are trying to make the ball, right? -- it's lying a little far out from the corner, and off the rail to assure a good hit consistently, and bad things can happen if you don't get a good light nick on that 5, i.e., you get under it too much or God forbid you miss it completely and sell out either the 15 or the ball you have to spot because you missed your kick. Soft-rolling the kick on the 14 if you miss a rail or ball, so what, you just took a scratch to a good spot -- maybe even under the 5 enough that Tony could not even see the 15 for the straight back.
