don't know craig, the poll is for if u would use ets if it was passed, but yes rings are expansive but there would be a saving on rubbers, once ets rings are bought its the losses that are going to be costly, but there again what would be the saving on rubbers, which are not reuseable, look at the balance sheets of organisations and see what it cost for rubbers for a season, remember ets rings are there apart from losses for good.
