I'm usong "cswing'. I looked at:

V1, JC Video and Golf coach.......

I downloaded and tried JC, V1 and cswing.

Cswing had the drawing tools I liked including angles like 56 degrees, had plenty of pro golfers to view, captured video from my camcorder to my laptop ok and I think, had the biggest viewable screen not including their toolbars and such.

It's great. I now have an idea what to work on with my swing rather than just going to the range and hitting thousands of balls.

Glad to answer any questions.
