Perfect is the enemy of good enough.
I do strive to be exacting on my lines, but on certain cuts I talk to myself saying I can go off the line and be a little creative. But yes, straight lines I try and nail my lines, as that can show up as a glaring error sometimes.
My go-to is also Flying Dutchman, but the Ultra Reverse #5. However, I am also using #1-7's as needed.
A few of my videos are from direct questions asked of me and I figured a video will help them, so I can show how I do it. My way is NOT the right way, but my way which is an amalgamation of other peoples techniques. Take what works for you, then it is a win.
