good find by the way. A few weeks ago and I wouldn't have know it was hackberry. Right before ojam I ended up with two 18in. Logs 66in. and 72in. I split one up and took it down to a ring, sealed the back, and then worked it down to profile @ ojam and a few days after I got home it curled itself into perfect reflex... Then passed that and went to about 8 1/2 in. of reflex. The ones I split, chased to a ring and left full size curled nicly into 2 inches or so of reflex. Very nice stuff.
