All 3 of these help me. I'm no bench expert, but I would give them a shot. Perhaps someone who knows more can comment on them.
The bottom line is that they help me keep a tight overall torso and I feel more recoil/power.
Do this....also think about when you drive the bar up, that you use your legs and push yourself away from the bar...rather than pushing the bar away from you....also...as J_byrd said speed is developed over time...lots of time....try lowering the weights some and focus on moving the bar FAST...then moving up 5 pounds the next week and try to get the same feeling...I'm not sure what kind of training program you are running, but as a generic training outline, thats what I would do.
