I pretty much answered this in the previous post I wrote. 339. No, I now wouldnt shoot it as a Z banger, because it is laying to run short, I would do something else, probably the 4 ball 3 in the side.
Following my own precepts I would move the 4 ball from its prestigious position no matter what.

Allow me to rebut your strategy with my thoughts and explain my reasons.
Your second option with moving the 4 ball imo is incorrect, allow me to explain. First, the angle for your three in the side with the 4 ball will place the degree of difficulty with following down table with the cue ball, on a scale from 1 to 10, (with 10 being the most difficult) about a 9-1/2
So that shot would be not one of my options.
Then you say that you would move the 4 ball "no matter what" Well I happen to think that the position of the 4 ball favors the player with the lead, allow me to explain. The position of the 4 ball will make it very difficult for Alex to pocket the 3 ball, a ball that surely you won't want to pocket. So actually the position of the 4 ball is advantageous for the player with the 4 to 0 lead. Furthermore the 4 ball can only be banked in two pockets, cross side, or long cross corner. Not exactly a ball that is positioned conveniently for running balls.
If you somehow would agree that the 4 ball at this time is not an option because of the reasons I explained then you have to look at either the 7 or 8 balls, as possible options, correct?
Lets first look at the 8 ball and play my choice (rolling the 8 ball under the 7 ball.) If hit reasonably well the 8 ball will block any two in the side options for both the 7 and 8 balls. And if that's true then Alex will be forced to play conservatively by rolling softly on the 7 ball or shoot your 4 ball from the position it's in now.
Lets now look at the 7 ball as an option. I like the choice that LVC shot with the 7 ball, because he has the skills to execute it. Plus he's not giving up a shot if the ball is missed.
So when I took a fair look at the situation, I decided that the safety on rolling the 8 ball under the 7 ball was the right shot for me. It got a lot done with no risk, plus I have my opponent playing the way I want him to play..conservatively.
