I guess it was my first experience with WP chain. boss picked upa bunch of the full comp stuff. I was running a 660/25'' at the time. So I put a new loop on the saw one morning, gathered up all my stuff & hiked down to where i was cutting. Started with a nice red oak 40 or so inches in diameter. went to let the saw eat & it darn near fell off the tree, like when a chain is really dull. So I thought that was strange but kept cutting. after 10 seconds I realized that something was not right. the saw was barley cutting... So i re did all the teeth & lowered the drags. All that took about 20 minutes. it really ticked me off that I had to completely re do a brand new chain first thing. After I leave that pickup & get in the woods, I want to get down...
So after being filed, it cut alot faster, but it still felt like some old chipper chain compared to a stihl chain or even an oregon chain. It went dull quicker too, I noticed that the teeth where rather brittle as well. Some teeth had lost there corners, it looked like they had just fallen off no sign of hitting anything either.
i ran WP chain for about 3 months, never had fun with it. Il take some RSF or RSLF all day, its worth the extra $$s. . .
