I'm finishing up the rocket build for my L3 attempt. I've built a LOC VII. I've built relatively heavy (glassed airframe, full length coupler, redundant electronics, etc) and expect my dry weight to be around 25-30 pounds. I purchased a pair of 1/4" tubular Kevlar recovery harnesses from LOC when I ordered the kit. These ones (1/4" 25 Foot): https://locprecision.com/collections/model-rocket-recovery/products/tubular-kevlar-shock-cord
I'm second guessing the diameter/strength of my choice and am wondering if I should upsize. The 1/4" LOC harness says its good to 1900 pounds. I've found these harnesses on Wildman's site, which are significantly stronger: https://wildmanrocketry.com/collections/onebadhawk-harnesses/products/obh-011
These 1/2" harnesses are rated at 7200 pounds.
Assuming the rocket is on the heavy side at 30 pounds, the 1/4" Kevlar is good to ~63g decel, and the 1/2" Kevlar is good to ~240g.
I do have a case of over-analyzing everything right now, but this is one that is simple enough to upgrade. What are people's opinions on the strength required?
