Just returned from seeing a stone in person that was hand picked for myself to view.... the stone was alive from every angle but scores a really bad HCA of 5.7... any advice...
Yep, that stone should have some leakage with that 41.6 pav angle. It needed to be at 41.0 and could possibly have been okay up to 41.2. But I wouldn't buy a stone with those numbers because I know there are better ones available.
I'd leave it....But if you saw it in person, and you liked it and it fit the bill on everything else, then sure. 2 on the hca is what's preferred and anything under 2 is the best.
