I think there is 3 rough groups, i agree the low end one are usually pretty flexible and light due to less padding, i then think there is a group in the middle where padding is added without much though making them heavier and less flexible, however i then think there is a top band, the "test match protection" where they have been designed well so that a large amount of padding is still light (in most cases) and very flexible like the low end ones, like the newbery's people have bought on here. Whether you feel its worth spending that much more for it is up to us individually, but i know the people's who have just bought the newbery's off ebay wont go cheap and nasty again!
