As one of the few people on the forum that has had one, I would discourage the blade. There’s a reason it’s often discounted.
Manufacturing quality questionable
The top dump is exposed
The way the dumps and inflator elbow joins with the wing cover meant two of my three dumps had issues or are liable to poke through (SF replaced them, the seal of the flanges depended on the poorly made wing cover)
There is no baffle in the wing so it balloons and the lift bubble is too high
Installation of loop bungees (as per the setup guide) mean the length of the bungees change when the wing is inflated
Weight “plate” or weight pockets do not let the weight sit in the center
Inflator parts aren’t compatible with the OEM inflator most others use
Harness plates aren’t shaped well
The way the dumps pull out of the OPV if you’re running it over your shoulder makes it more like to fray.
If it was the only SM wing I could buy I would make my own using an MSR bag, but hey maybe Horst improved it
