I am gonna kind stand up for both points being made here.
There is nothing wrong with the Diablos for what we need them to do. However it does look like they 'may' become harder to source and more expensive. They are hopfully being replaced by the Rosso at some point and providing it is in the right rating and size and a suitable price then there is no reason not to continue with them.
However that does not preclude the RC or others - in discussion with the RC -investigating alternatives and putting these forward for consideration for future years. Whether thay are accepted should be down to a number of key features that will be agreed when the time arrives.
The point is that the time to start considering this is now so we don't get caught out next year if things change and we are not in a position to source an alternative at short notice.
As to whether Maxxis are right or wrong.. I don't know tbh! but lets not just dismiss things based on emotion and personalities.
an analogy...
Lamborghini used to make tractors and if you had asked anyone at the time you would have probably been dismissed if you suggested the make a sports car but when they did start they were quite good at it
