"I would think that if anything, our product would probably be softer than most and that's pretty consistent with the industry as a whole in Aussie as we've successfully been using poly as a direct replacement for rubber for many years. The Whiteline Plus range was developed as an extension of that with "progression" being pretty important in the design. For those interested in you can take a look at

So whiteline is good for street use?
