As usual, Gaines speaks the truth. Also, the last(outside) strings(mains and crosses) will not have 'opposing' weaves on the 'other' side to offer resistance...thus the outside strings are easier to move and appear looser than they actually are. As such, they will always appear to be at a lower tension no matter what tricks are employed in tying off. As an important PS...I would choose just about any OTHER tie-off implement rather than needle-nose. I've seen more than a couple of injuries occur when the string broke or needle-nose slipped and suddenly a very sharp tool is headed faceward! It may not happen for 9,999 string jobs but it only takes one to mangle a body part. Let's be careful out there!
