I ordered and received five packs of them. Have not shot them yet but expect they will fly great. They are small but with six blades and the rotation of a single bevel (will be guided by vanes with a hard helical as well), plus the tissue pushing scoops, I’m betting they produce a surprisingly larger wound.
As far as sharpness, the ones I received are very sharp.
Also, I weighed all 15 heads. They all came in within less than a grain of each other and 11 were exactly the same weight.
I’m going to do some testing on these and a few other heads once I get all my bows sighted to the new arrow I built. Will update on how these did.
