Tim...the "Premier" you have is of fibreglass construction whilst the new one is made from an entirely different process and therefore materials. Your one will be lighter than the new premier model due to this.We realise we cant produce a product that is as light as the Elite/RAW shells in plastics which is what the premier and pro will be made from (all be it a lot more advanced materials than the bog standard "washing up bowl" materials that other choose to use).
That RAW lid was very comfortable, i have to say... I will have to start saving up
