Spectra lifeline confusion

[rockfordwoods]

I am getting ready to change over this weekend, but in thinking about the work to be done, I became confused. I will be using Johnson fittings throughout. For each length I had planned to splice the line to the closed end fitting on each end. This morning I realized that I could only do that for one end of the line using a brummel of the open variety poking each end through the other. Since for the second splice I will not have both ends of the line available, I will be unable to make a locked brummel of any sort as it would require passing the fitting through the rope. Looking at the Johnson advertising, they show splices on both ends of the rope. So would they have used a plain bury on the second end just to show how pretty everything is? Am I thinking correctly that the only way to accommodate the second end is with an empty locked splice ring hitched through the eye of the fitting or with a deadeye and lashing? If using a ring hitch, does that not create as much loss of line strength as a knot?
