Awww... Don't mind the other fellas... They're just giving you a hard time. If you start producing video, where you're asking questions on a tree, or cut--they'll likely not smell blood, and go in for the kill.
We love good video with questions!! Like, "How does my stump look?" "What could I have done better?" Etcetera.
I do suggest you do some reading here on chain filing/grinding. After watching your video's, I know your chain can use some work. I know a lot of guys here that thought they had it mastered... And ended up learning a lot, and their chains now show it.
You should try and slow down a bit too... Don't rush through the cut... It gives you more time to evaluate the situation, and make decisions based on what's presented. Like I was telling another member here a week or so ago in a PM...
"I'd rather be slow and alive, rather than fast and dead."
