Nah, call shot call safe is lame. I thought I'd like it, but it's only good on paper.
The biggest problem with it is, players think it eliminates luck in the game.
But it doesn't, it just eliminates GOOD luck for the shooter,
and creates BAD luck to replace it.
You kick in a ball accidentally, it's not reward, or a neutral situation, it's a penalty for the shooter.
You try to kick in a ball and miss, the guy in the chair has control of the table AND the option.
Instead of the incoming player catching a shitty roll because you missed, YOU now catch the shitty roll.
The luck isn't gone, it's just randomly shifted from one player to the other.
And yes, the removal of the 2-way shot arguably removes skill from the game.
It also works against years of instincts... we all have subconsciously developed the skill
to miss the correct way, to increase the odds of not selling out.
Now that skill works against the shooter, and gives all the power to the guy in the chair.
Why does he deserve extra consideration after you miss?
Ultimately, it's less fun, even if you want to argue it's more fair. Fair is overrated.
Fair is, let's make every race go to 140 games just to be REALLY SAFE.
Fair is, let's all forget rotation and everyone has to play straight pool round robins.
Fair is, let's eliminate the break, open with a safety, and play on 12 foot tables with tiny pockets.
At some point, a player just has to accept that rolls are part of the game,
a tournament is not always about the absolute best player winning every time,
and fun still matters even if you've got an entry fee at stake.
