At first I have to say that I don't like the comet trail to make the ball visible because to me it looks very unnatural. So in the past I played with the follow cam which is also quite unnatural but at least I could see the ball.
Now after the update with the follow cam the ball takes a very disturbing vertical drop near the end of the flight and falls down like a stone. To solve this I changed to the player cam with ball tracer comet and fiddled a bit around what might be the best solution fo me. In the end I found out that a comet trail length of 0.07 m and the landing snap camera is currently the best compromise between visiblility and realism. The tracer as small as can be to see the ball from the tee to the landing spot.
An nice enhancement would be if the comet trail could be automatically turned off when the view changes to the landing snap cam because here the ball is good enough visible without a comet trail.
Another improvement to the visibility as someone mentioned in a another post would be if the ball could change from pale (white) to dark (grey/black) and backwards depending on the background.
Overall the update is looking very good and I'm sure the devs will enhance and fine tune the unavoidable small bugs of such a big update.
Keep up the good work.
