My buddy has one of the thin SS plates, it feels as light or ever lighter than my Aluminum one, I would prefer one to my aluminum just for the corrosion resistance.It looks identical in shape to the standard thickness .125 plates, just thinner.
I may or may not make more, don’t know yet. I haven’t received any feedback either way to gauge the popularity.
I think they’re better than aluminum since the weight of the plate is at least usable and goes less neutral in the water.
