These putters are not just another variation of putters that experiment with new materials. They represent something completely new - a concept that is fundamentally different from what is known from “modern” or conventional putters. Their full potential unfolds when they are played with reduced grip pressure. As these putters generate a deliberately low ball acceleration, it often takes a few minutes of familiarization to then measure the putt length more precisely than you have probably ever experienced before. When used correctly, they provide feedback that is downright addictive - a feeling that is immediately missing when you return to a conventional, heavier putter. If you internalize the concept and apply it consistently, you will experience a new dimension of putting and develop an opinion about it that will undoubtedly be heard.
No, it is one of the hardest high-tech polymers in existence and is often used in aircraft, space travel and industry where high resilience and abrasion resistance are required. It is also temperature resistant. It is harder than many metals. However, if you insert a screw crookedly into the thread and then tighten it with force, the thread will break, just like a steel thread.
For example, if the putting mat pulls to the left despite a straight start, any further attempts to aim for the hole will also go to the left. The solution is to either ensure a straight putting mat or aim to the right. The exception, of course, is if you want to portray something poorly, then you can keep aiming at the hole, even though you can see that balls start straight and then turn left later.
