Techline Ridgeline Bury?

So I know it's supposed to be 21 times diameter, but what about for ridgelines? Surely those don't need to be as strong, so surely I can save some weight there, right?

My last ASRL i went 6". Held just great.

Typically, buries for dyneema lines are ~3 fids (3-3.5). A fid is 21 times the line diameter so 3 x 21 = 63.

Since I don't know your line diameter, let's use 1.9 mm which = 0.0748".

That would give you a bury of 63 x 0.0748" = 4.71".

1.9 mm Tech Line (DIYgearsupply) weighs 0.018 oz/ft so the 4.71" bury uses 0.0071 oz of line.

Shortening the bury isn't going to save much.

For 1.2 mm tech line, the bury weighs 0.0022 oz.

Don't forget to add 1/2 fid or so for the taper. Most line failures occur where the line changes diameter suddenly due to too short a taper.

So... 4.71 inches for the fixed eye and UCR right?

Would it be wrong to make the stopper buries much shorter?

If you're talking about the back splices on the loose ends, yes, they hold nothing and can be shorter.

The adjustable bury in a UCR is usually longer than in a whoopie sling because it is only fully tensioned on one end. Hopefully someone with more UCR experience will chime in.
