Great.
The finish Swivel - is that to avoid steering/blocking or just a means to a nice finish?

My impressions;

All of the above. After you get past both arms straight you can't do anything but swivel.

If you develope a nice smooth swivel then there is no way to steer or block. A nice smooth swivel is like soft butter. Nothing else is happening. Smooth, coasting.

A good swivel will make you smile before you look at the ball flight.
