360degree straight grain - yes.
360degree Birdseye - never
Think of the bundle of straw - you can only get the end grain only at both ends of the bundle - never 360degrees.
Back in the mid-1970s I chanced upon a pair of Lorenzos in a B&M.
One had beautiful Birdseye on both flanks but was almost twice the price of its much plainer "twin".
I bought the cheaper "plain Jane", being an impoverished student at the time.
To my regret, even till this day.
That was the very first time I was aware of grain in a pipe.
Even as a novice my eye was drawn to the beauty of the Birdseye.
