Long Arms Through Impact

In my daily perusal of my favorite golf blogs, Richie3Jack's contained something in particular that caught my eye. He was talking about people's obsession with creating lag (and hence, power) in their golf swings and made a reference to 'running out of right arm' and that this was something that Homer Kelley talked about in quite a bit in his seminal text, 'The Golfing Machine'. I've noticed lately in my garage golf swing laboratory that some of my best feeling shots have something I'll call 'Long Arms Through Impact'. It sounds like something similar to what Mr. Kelly was explaining, I believe. Let me explain: when I truly feel like I've created good extension and a powerful release through impact, my arms feel very "long". Its like my left forearm has become an extension of my left wrist and hand (and ultimately, the shaft) and they're helping to sling the ball off the club face in a very forceful way towards the target. This is a feeling that I'd like to replicate as much as possible--doing so is another matter entirely, however.
Now back to Richie3Jack...he says "And I think what happens is often times when you try to create too much forward shaft lean and you 'run out of right arm', that running out of right arm causes golfer's to flip. Yes, trying to create too much shaft lean I believe helps *cause* throwaway." This sounds exactly like what I'm trying to avoid. Funny how this is all coming together, isn't it? Thanks, Mr. 3Jack.
