I'm a decent jumper, but I don't know a single person who thinks that having to pull out a jump cue because they missed position is preferable to not missing the position in the first place.
Not sure if I implied something otherwise but if I did, it wasn't intended.
If you miss position you're going to be punished. How much that punishment is depends on your skill. Whether those skills includes jumping, kicking, or otherwise extracting yourself, those who are better are going to suffer less punishment than those who are not.
Agreed.... However we're talking about a failure to perform shape that would normally end an inning, versus a simplistic jump that continues an inning that could potentially involve additional racks. If a player screws up so badly that they can't make the ball they were trying to make good on, then I don't think it inappropriate to believe their inning should end because of it.
Yes of course if a player puts effort into the skill of jumping, then they should be able to utilize that skill. However fundamentally speaking, jumping prowess shouldn't supersede CB control in terms of importance.
Regardless though, in every case, you're at more of a disadvantage to miss shape than you would be to have played it better in the first place.
It isn't a question if you're at a disadvantage or not. Simply a matter of how severely disadvantaged you are. In most cases, without a jump cue the odds are that you inning will end.
We should remind ourselves that the OP was referencing "pro play". I view a first approach rule to jump cues no differently than 4" pockets.
