The flop we're talking about is from the slack introduced into the line by the piece tipping over. The porty is upright, held by the tension put in the line, then it topples over as the line slacks, then rips back upright as the load hits it. I just prefer a stationary bollard when rigging out stuff over 1000#.I always just tighten the line first, then take wraps. Never noticed it flopping much...? You can get decent tension just buy sweating the line a bit first.
