Each of these eights is 140±4 mm. tall and 75±1 mm. wide. Their weights fall in the 128±8 g. range. These are normal manufacturing variations that have no practical significance. They are about the same size and weight as Standard, Full Size, Forged Eights.

The shafts on these eights are rather fat and well-rounded, with an indentation on each side that usually have raised markings. Although similar, these eights are not identical, and close inspection will reveal some minor differences in their shapes. None of these affect their performance to any noticeable degree.

The rope tends to run smoothly on these eights. They provide a good rope contact area for dissipating heat. Their soft finishes wear faster than a hard-anodized finish would, but the fat shafts have more than adequate margin for accommodating reasonable wear.

None of these eights have slots for sticht-type belaying, and their round eyes are not designed for that purpose.
