So it seems to depend on how many strands you want to use. 8125 is supposed to be marginally faster, but differences between different types of hmpe are hard to judge. Both should do okay for recurve strings AFAIK.Question: What is the difference in strength between Dynaflight and 8125? I previously made my strings and cables out of Dynaflight. My strings were made with 16 strands and cables were 14 strands. Now I have started to use 8125 in which I made a string consisting of 18 strands, and I am wondering if 14 strands for a cable would be strong enough because of the smaller diameter. Could you tell me which is faster and more durable, no.2d.016 end serving or no.2s.018 end serve?
Answer: Both DynaFLIGHT 97 and 8125 are made from the highest quality Dyneema? yarn. 97 with its larger diameter is about 23% stronger than 8125, so 18 strands of 8125 would give you similar strength to 16 of 97. Both materials have excellent durability.
We recommend 18 strands of 8125, perhaps 20 in your cables, but consider putting 452X in your cables.
8125 is the faster string material.
If you use too few strands, you are likely to get some "creep"; particularly on the high poundage bows at high temperatures.
Regarding end serving, our 3D and 2S have similar strength and durability. The 3D is popular because of its smaller diameter and 3 ply rounder construction; it seems to serve tighter. Halo .014 or 008" Spectra are other options.
