My guess is we hit the 2hbh very similar, and this is just a "lost in translation" thing. Also note, I'm just 2 years (and not much match play) in my attempted conversion to 2hbh... so I don't speak from years experience. That said ... I'm in the period where I'm still having to think about the stroke.
I am right handed. I hit
bent (right)/
straight|flex *** (left) ... designation based on arm position at contact.
A couple of observations:
- the left arm doesn't start from straight. It starts from that weak T Rex arm thing (borrowed that from Jolly). So it is in the process of extending from backswing to contact.
- I think we agree on the shoulder arm triangle thing working together at the start of the swing. To me, at the start, there is no left push vs right pull thing going on. I think the start of the turn is just a shoulder turn which brings the right arm and hand along. That right hand is attached to the racquet, it is in fact pulling the racquet. I think I just react against the idea it's a pull with right arm muscles ... maybe like the finishing of a 1hbh. I don't feel that in mine.
- to me, the first half of the forward swing feels like a shoulder turned 1hbh ... with the right arm supporting most of the racquet... with the left arm doing it's T Rex thing. Then part way into the swing (we all vary) ... the left arm fires/extends into contact. I think the left arm is doing it's least at the backswing, and the right arm is doing it's least a contact (both doing a lot to even support the weight and maintain arm triangle positions).
No matter how we vary ... we all have that 20lbs of arm triangle thing going on. No way we can pull that off without the shoulders and arms working A LOT together. We throw that arm triangle from our uncoiling. That's why I really never believe it's just a left handed FH. Can't be ... that other arm weighs a lot ... your grip is now made up of two hands, and your arm-to-racquet is now two arms. I believe I boost the arm triangle speed with the left arm (I guess I would call that pushing ... have to think about that). I also think I hit the ball with my left hand ... but it's not exactly the same as a FH. That other hand is there.
Here is some snapshots from my ball machine session this morning. This is what I mean by the left arm extending into contact. Maybe more power than swinging the extended lever you were talking about.
*** Looks like my left arm doesn't get all the way straight, at least on this shot. Maybe if I straighten it I will quit hitting so many near the tip.
Here is the video from my ball machine session this morning. This was the "good stretch". I'm at the point where I can almost look like I know what I'm doing, and then completely spray one. That's why I keep bagging the 2hbh in singles ... my 1hbh slice misses are not as embarrassing.
Feel free to give me any tips (anyone else also). Wasn't this thread about 2hbh "power". I need more of that. Who doesn't.
Edit: it also occurs to me we get the benefit of much of the weight of the arm triangle hanging down in the initiation of the swing... like an elephant swinging it's trunk. Even on higher balls, you have some angle, and upper arms down. Same with swinging a bat ... upper arms down. So when I talk about 20+ lbs of arms and racquet being supported, that's not in the fully extended position at the start of the swing. I tend to think of racquet drops as timing and not an addition to power. However ... when you see Fed swing his FH with straight down ... and 2hbh triangles down in the swing, that has to be pendulum aided.
