I thought the video was great. Really solid info that needs to be well aired. A lot of the concepts are going to be familiar to the nerdier of us - but I think the video does a really good job of explaining this stuff to an audience that hasn't really given this any prior thought at all.
What I'm really hoping for now is a follow up. The video provides a really strong conceptual framework for how impact works. What would be great is to pull together some practical conclusions and guidelines for people to practice with.
For example - I think Brian says that, for his six iron and his relatively steep AoA, he needs to aim about 25 feet left of target. I wonder whether it's possible to give parameters that people can work within - say, most practical AoAs are going to result in a plane line aimed left between, say 5 and 30 feet?
Then again, what's the practical relationship between aim and HSP? I guess someone could line up perfectly parallel to their target line and then swing a little OTT and zero-out their path that way. Probably not wrong in itself - but are there limits?
How should alignment vary through the bag? Driver was dealt with, but is a special case where the ball is teed. But if you get your set-up and swing dialed for a 6 iron, what should you expect to change for long irons, fw woods or short irons.
What about face alignment? I suppose that a perfectly consistent grip and release would result in perfectly consistent clubface alignment at the lowpoint of the swing. But the point here is that different clubs are reaching impact at different points in their arc. Presumably, the steeper the AoA the more open the clubface. How do you control or allow for this hitting different clubs out on the course?
I think Brian did a great job of showing how, using trackman, you would go about zeroing out your swing for one particular club. Is it a good strategy to even try and do this right through the bag? Is it better to try and minimise the changes in your set up and swing, and accept some predictable changes in your ballflight with different clubs? I even wonder, do sweepers have an easier time of it than diggers, because their shallow angle of attack results in less variation in their impact alignments?
