Any of these shots could sell out.
If hit too hard, the ball rebounds back to your opponents side if missed. Pocket speed is most important.
Practicing these ALOT increases your percentages.
#1 is super easy on tight pockets. 4 up 4 1/2 inches.
The closer the pocket gets to 5 inches, you have to throw the ball more, and it may not be available on certain tables.
This shot relies on proper cross over speed,
and a touch of follow to play the CB off the nose of the bottom rail.
If the pocket is too big, you can't miss the scratch by hitting the rail. So it doesn't exist there.
If you're comfortable with the kick bank adding inside English then that's great option on big pocket tables.
Tom Wirth encourages those shots allot on YouTube. Maybe check him out.
The other 2 shots are near identical imo.
Both are center ball shots; if that's my last ball, and no further
maneuvering is required. English to get around the table is the only reason I'd get fancy on those banks.
If those are end game shots, it's an easy call once you get more familiar with the game.
**#3 I may put a hair of running English depending on the cloth and rails.
I kick allot. So much so, that I've influenced some very talented players to rethink how they address certain shots now.
They'd say it's a low percentage shot in the past.
Where as now, after seeing me make aggressive shots regularly, kicking a ball cross corner on the bottom rail doesn't mean an auto sell out anymore.
Main thing is to just hit these shots dozens of times to develop the feel for them and establish some muscle memory.
