Just to demonstrate how important it is to choose the right ferrule material if you really want to obtain good low deflection performance. Knowing that a ferrule on a carbon shaft measures approximately 2 to 3 cm3 depending on the diameter of the shaft, a difference in material density, for example between the Hydex 202 and the Juma, is 0.4g/cm3 according to the B.D. website, ends up with about 1 gram difference at the end. And if we look at the table below we can see that a difference of 1 gram in the first inch represents 22.3% more deflection. So in some way every little detail is important to achieve your goals.
