Le Pro is the softest tip I have ever played with. I learned early on that a hard tip gives you better control of english. I have shot with soft tips in trying other peoples cues, and they are 'spongy' and unpredictable. Many misconceptions exist about soft tips, and that is why so many amateurs use them. Most of the pros, a large majority, play with a medium to hard tip, and there has to be a reason why!!!
It's like comparing a normal car's steering to a sports car's steering. The sports car's steering is so much better response.
