The TriLink loops I had would "walk" left & right before biting bucking beech logs.
That had me baffled so I took a close look at the cutters and found the cause for all of it - tooth stamping geometry.
Oregon (and other quality chains) have the cutters outer corner higher than the cutters inner edge, that makes it bite ferociously when sharp, but also dull instantly when hitting dirt.
The TriLink I had was the exact opposite in terms of tooth/cutter geometry and it made it a poor performing chain, yet helped it staying marginally sharp when hitting dirt since the cutters outer corner was not the leading point!
I made it look extreme just to portrait what I mean, it was subtle but somewhat like this.

Funny thing, the TriLink tooth geometry actually helped the outer corner "stay sharp" longer.
Unfortunately it severely impacted cutting speed and self feeding which I am a huge fan of.
