Quarter sawing is a HUGE waste of wood and very time consuming.
You actually end up with several quarter sawn pieces ( radial grain ) sawing in the plain saw method per log anyway, which gives you primarily tangential grain.. ..so you could always pick to use only those pieces if desired.
I was asked why I alternated "Crowns" I went on to explain what I was actually doing and why...and also why it probably wasn't important in this case any way.
But you are 100% correct that would and does cure 99% of the issue with cupping.
I don't as of yet own my own saw mill...my neighbor does...Its all I can do to get him to cut for me about once a year let alone get real demanding about it..
