I agree with Nick--use a longer bury on the Loopie.
If the Loopie is always used correctly (a big if), meaning it is always used in the choker configuration and the spliced section is always formed into a bight to capture the hardware-attachment loop (see the Sherrill video), then Nick's advice is probably unnecessary.
But someone is going to treat the Loopie as just a handy adjustable loop and employ it in a straight-pull situation. This is emphatically unsafe, and it is especially unsafe with the standard one-fid-length sleeve. If you double the sleeve length and want to use the Loopie for a straight pull, you will still want a bight in the spliced section for one of the pull points. For maximum safety the pull point should not be in the middle of the spliced section, but close to the end opposite where the long adjustment tail emerges. This way the pressure at the pull point performs the function that stitching would perform in a normal hollow-braid splice.
