dynema vs articulated metal bridles

My own personal opinion is in favor of American (and South African) style dynema or spectra. You won't cut your hands on them, they make virtually no noise while firing, or at any other time (e.g. they don't clank against the barrel while the gun is unloaded).

Plus you can use a shark finned shaft, or at least a shaft with shallower grooves. That means the shaft will be stronger since it's not almost cut in half already.

Someone will probably chime in with a ballistics opinion on why metal is better, but it's a 0.000002% theoretical improvement.

Only downside is they get worn down faster than metal, but I personally find the rubber goes slack and loses its power long before then. I replace powerbands frequently enough to maintain max power that metal isn't worth the investment or the digit loss. Plus, DIY stuff like making your own powerbands is half the fun.

I have an HF and the metal bone nicked up the barrel on mine. I switched out to dyneema. It is more quiet. Make sure you file the notches on the shaft, otherwise it will cut up a soft wishbone.

There are a few ups to metal wishbones,like the rubber pull will always be aligned,and you can also sight better straight down the shaft.

I really like both ways,what I do is keep my euros with metal and the railguns with line.
