These look great and can be adjusted from both sides but slip and dont hold there length causing a big fat are to be dragged along the water anyone else ..........
Been using NP Race adjustable harness lines (black),no problems at all
easy to adjust on the water and no slippage.
Think they all slip except maybe the metal buckle ones but they corrode after a while.
Got some Maui ones there not too bad.
The older ones are ok. The latest batch of adjustable lines slip easily - they're duds. I'm taking mine back to the store.
