tongzilla - this was one of the areas that Lynn and Ted helped me with at OCN. I had been loading for hitting (not allowing the rotation) but with basically everything else I had a pure swingers pattern.
Getting back the startup swivel was an odd feel at first, because I had worked into an underplane backswing and held off the rotation. There were two key feels that I focused on that once I got them back made swinging fun again....
One was feeling the toe 'up' position at halfway back. Not just the alignment, but getting more 'up plane', which I could only do if I first, and immediately, had a startup swivel. The second was getting my extensor action back. I had been underplane and was getting lazy with my extensor action.
The startup swivel really feels like it begins with the left shoulder, not so much of a hands only roll, but a roll of the entire lever assembly.
Two training aids that give this feel very well - the Medicus and the swing glyde. A momentus 'can' give this feel, if you allow it to, as can a figure 8 strap or swing jacket, but the later two aren't as direct. If you know the feel, its there with them, but they can be tricked.
Hope this helps - it really is a bit of a 'leap' to get that startup swivel going properly, but if you can do it on plane it is fairly easy to groove.
