This is going to start sounding like I'm bragging but I'm not. I'm just trying to be encouraging. If I can do it, then you can do it.
I have shot shots from off of the side pocket points but not that one until it was posted here a little while back. I went to the table & set it up & shot it. I missed it the 1st. time to the short rail side. Then I hit the long rail like Efren but I missed the ball. The 3rd. attempt I made it 'better' than Efren, because I went straight into the ball without hitting the rail.
I probably might have tried going to the long rail with a ton of low inside english for a single rail kick before I would have ever tried that shot. Especially given the circumstances. But...he saw that as better.
It should me that it can certainly be done & then I quickly learned that I can do it. If I can do it , 'you' can do it. We can 'all' do it. It's just a shot.
The question is, can we see it & decide to shoot in less than 10 second's like Efren did. I think the answer is no.
Best Wishes to All,
