Injuries aside, down on the stick, way back grip, just simplifies the whole process. Aiming is easier*, shooting is easier**, speed control is easier***.
* Every thing is right out in front of you referencing itself. If you're one of those that needs to look at the pocket, TS. When you're down to shoot is too late.
**With a long bridge, you simply put the tip up to the cue ball - on the aim line of course. Now you have learned the impact coordinates. To shoot, pull cue back and stroke the cue linearly forward to where the tip started. The strike is almost a given.
