We had an ironworks one and found it to be heavy, especially when pure Dorset Downs were in it. Also, due to their shorter legs, the bars that were supposed to go under the belly, jabbed them instead. We did look at a different type that has 2 big circles on it but we didn't have the money to buy it. In the end, we managed to turn the sheep between us by hand (eventually crossing down the size to Dorset x Shetland - decent size, longer leg and lighter, but still able to lamb in winter).
