Those are great looking trees. I've found a number of place that had groves of HHB like that and was able to harvest many nice trees but the percentage of good straight grain trees was probably less than 5%, all the others had too much twist. That first photo looks like a humdinger of a tree but from looking at the picture I do believe that it has a fair bit of right hand twist. Still, if handled properly you could still make use of the wood to make many nice bows
