> First of all, just because in frame #4 the knob is pointed at the pitcher when that frame was shot does not mean the bat has linear rather than rotational velocity. If you were swinging a ball around on a string and we took a picture that looked straight down the string, you would not say the string had linear rather than rotational velocity or momentum.

That is why I made the video ( http://webpages.charter.net/nickkio/HandPath/ ) showing what happens when a bat is accelerated linearly (no torque applied to bring the bat-head around). That is why I asked you to “explained how "Linear Momentum" has a positive effect on the swing”.

> Jack I went out for a hitting session the other day and I did a little experiment,it had to do with loading and what kind of results would be achieved with different loads.A clip of Paul molitor with his rear elbow starting tight to his ribs is what got me thinking about it,since this is very different than what we see with the high elbow in most M.L. hitters.I did my normal load as we see in the Gurrero clip and drove the ball will over 300 feet off the tee.I then did one like Pujols where he starts level with shoulders then raises up and back with elbow,again good results but not comfortable to me.Next I put the elbow tight to my side as I saw in molitor but I also did as he did and drew it up and back about 30 degrees[which is still low.I was surprised that I hit the ball very hard and nearly as far with this method.Last I used the bow string method which may be different for you than as I perceive it and the elbow went straight toward catcher no pulling back toward dugout behind me,the results were quite dismal compared to the others.
My thought on this was that the 1st 3 all loaded the front shoulder identical for me the last did not load the front shoulder well[slack].In fact my 1 arm swing when loaded like the 1st 3 ways hit the ball further than the straigt back method with 2 hands.My conclusion to all this is that properly loading the front shoulder is what is important for my swing and your thumb idea does this for me as does the normal loads we see in swings and the extremes we see in pujols and molitor.
