Ray, no the edge's don't have to be perfectly identical but I feel like a 19 degree edge versus a 25 or 30 degree edge will make a big difference in the results. So I'm just saying lets all try and aim for 20. Ten on each side. 2-3 degrees wont break the bank, 10-15 will I think.
I've got some 1084 I can sell, lemme see how much though.
