Nice..yeah I think the LnR is awesome because once you get your forehand dialed you won't even think about how your wrist is, and things like that.
For example, on your first vid youtube was being slow, so it froze right where you were actually pointing the buttcap at the ball and about to swing to contact on the forehand. It looked perfect in that aspect.
Also my coach is pretty highly ranked and when I ask about all the nuances he tells me that those are there from my experience and not to worry about it. He fixed my backhand in one lesson..it was crazy. So I am just passing that perspective on to you as an alternative.
I would suggest preparing earlier to fix that contact point. Its just footwork really..boils down to fitness and the dedication to split step right before your opponent makes contact.
