[12 piece bucket]

Bucket,

As you quoted in your original post, any bend at Impact Fix should also be present at Impact. He doesn't start from Impact Fix, though - if he did, it'd probably look exactly like Impact!

You got me! Not really a Fix address is it? Do you have any down the line sequences? I'm looking at the one in a book called The Methods of Golf's Masters. He's definitely Arched at Start Down. Hard to tell if the Arched condition is maintained all the way down and through.
