How would they hold up for (dare i say) boring big hardwood. I can tell you right now that our bars can get seriously flexed trying to get a bore in on the uphill side while still having a respectably low stump, mother earth can get in the way, she can be rather slanted....
How about the sugihara bars?
And..... WHY IN THE WORLD DO THE POWERMATCH BARS HAVE THE STUPID ####IN HOLES IN THEM NOW THAT EVENTUALLY ALWAYS POP OUT AND THEN FOREVER BIND WITH SAWDUST IN YOUR CUT??????? I figure its for milling them out, something in their manufacture, but I think I'm gonna have to quit using them. I JB Weld them over once they pop out but those pop out too, eventually. I can get Stihl bars the same price, the only reason I dont use them all the time is the replacement tips are about $31 vs. about $14 for the Oregon tips
