Since your still cock blocking me on Youtube I figured I would drop this here Kenny. I don't mind sending biz your way and lining your pockets if someone might learn something.
I'm gonna keep this super chill and to the point Kenny-
You look to have bypass on all 3 undercuts. No matter how small the bypass always try and take the time to get your undercuts perfect. You will thank me later.
You cut all your hinge on the second tree. Alway be aware of where your tip is on your back-cut, and also slow down when your tree is going over. Just tickle your hinge if necessary. You also appear to have a some sort of follow through with your saw as your trees are going over. Follow through is great when were shooting a basketball or hitting a baseball, but not something you want to do when falling trees.
It looks like the last tree almost got away from you. It appears the bobcat saved it from going a little left on you. A look at the butt at
7:47 in the video tells the story as to why.
I commend you for busting out some wedges, but I would highly recommend you alway put 2 side by side whenever possible. That way if you spit a wedge you have a backup. If you spit a single wedge at the wrong time your tree can sit back, and that little bit of movement can be all that is needed to loose a tree over backwards. I would also learn to work your wedges a little more as your making your back-cut. Stop back-cutting for a moment and pound one wedge tight, then alternate between your 2 wedges and slowly start pushing your tree over. This can all be done in coordination with your tagline. When you know your got her, gentle work your hinge and send her on here way!
All in all some pretty good cutting, but you just need to tighten that shit up a little buddy. Always strive for perfection at the stump. Certainly can't fucking hurt. right?
