Tim - maybe I've just been lucky. Last frame I hand cut (power and push pull) 151 pieces, I had 1 that was 'sticky'.

Maybe its more of a supplier issue than a sawyer issue - perhaps the logs were in the yard for quite a while before being milled?

Last time (6 years ago?) I worked on round and square - the rounds were miserable to work with - layer just under bark (cambium?) was a mess. Wasn't until you got into the core that things were pleasant.
