All I'm saying is the jump cue isn't the magic wand everyone makes it out to be. Many times that "good hit" is a sell out and a loss.
I've never seen a pro, on tape or otherwise say they don't like to use jump cues. If there is, point me to them.
As for jumping full cue, do you believe a person using a hard tip has an advantage over someone using a soft tip? The discussion will end up being we should ban hard tips... or jumping altogether.
If you listen to interviews and commentary it's in there about them not liking jump cues. I don't know exact spots or matches to point you to, but every time someone asked a pro about jump cues the closest they have come to saying they liked them was "it's in the game so I use it" and many say "I would rather they did not but they are so I use them". Mark Wilson, Jeremy Jones, Earl I know say it often, any time you watch a jump shot, listen to what the commentators say about it and if there are interview questions about the jump cue, as long as they are not trying to say bad things due to the sponsorship product they use, the players say the same thing. But you can tell when someone is just trying to be nice vs someone that states what their actual beliefs are. Especially players over like 25.
No issue with using a hard tip, or jumping in general. Hard tips may make a jump shot easier, but not by that much, jump cues turn impossible shots or shots that normally take a lot of practice and skill into trivial ones. I just think they need to have a stricter weight and length limit on cues. If you can't have a 20 lb 50 inch long 12 inch wide bat in baseball we should not be having 65" cues or 30" 8 oz cues. The sport should be set up to have some sort of a difficulty level in the rules, not make it easier so everyone can do it, up to a point.
Pool like other sports evolved over time as we saw what worked and what was not so good, a jump cue introduced in pool is like some guy entering a car in NASCAR with a 200 hp advantage and no one saying anything, or having a player grab a smaller basketball to shoot a free throw. Look at the silliness caused by someone saying Brady used a ball with a tiny bit less air. Other sports have good equipment regulation, we should also. Golf you can't play properly the way it is without different clubs, it's like making a woodworker use only one tool for everything, but we sure as hell can play pool the way it just fine without jump cues. Just because some shots are harder than others does not mean it's a thing that we should make easier, there are simply harder shots one needs to play. If someone is on the rail far from the object ball they can't just say "oh it's far, I should be allowed to move it 6 inches off the rail", it's simply a hard shot they need to deal with somehow with what they have on hand, their skill.
Set a nice range where there are options for the players but not that it's something silly. Say 62" and 56" as max and min ratios, and limit weights to say 25oz (since that is what many of the heavy break cues are) and 16 oz minimum. That should be more than enough for tall or short players or just those that like a different size cue.
Many pro equipment standards are different than amateur or even college sports, I don't see why it would be an issue not to have jump cues outside of maybe trick shot events or fun circus events like Mosconi Cup. Any event ranked for "pro points" or whatever the latest point system is out there, pro level equipment standards are enforced. This way Joe McShooter league dude can still jump to his heart's content with a jump cue and make the cuemakers happy with sales and we are not seeing safety play or mistakes being ruined by jump cues at the pro level.
