Replicas of Rubber Tips

Hello, I want to clarify that this for metal fight performance tips. As the title says the rubber tips from 10 years ago are really limited. The only thing close to it are midfake rubber tips which some are inconsistent or just bad. I am working on replicating the rubber material, no luck yet but found another material that behaves similar in terms of attack or defense. The bad part of it is that is not as durable. When is a brand new copy, it behaves differently until the heat of the friction kind of reshapes it to have a good attack pattern. The only positive thing about the bad part is that it works like a warm tire which helps grip. I have 2 videos in the subreddit of BeybladeMetal. Thanks for reading will update as soon as possible.
