I believe this may have been covered back in one of the questions from page one of this thread. But, once the holes are drilled, this cores still holds great properties of imbalance from the moment arm. The self righting capability when compared to other cores after drilling, the SRC still has a greater self righting traits that remain. With both moment arm values and self righting traits still applicable across a wide varitey of drillings, the SRC as we have discussed helps give the bank greater amount of angularity compared to similiar surface balls, with similiar RG, and similiar diff rg that are on the market today.
