Got the Harmon plane laser now. My grips are midsize so I am not able to fit it on those. Have to use another club when practicing with the laser, but I can live with that.

Tip regarding the butt laser: I put two chairs chairs 2 feet apart & put the shaft across both backrests. Laser dot on a wall some 8 yards away. Turning the shaft I noticed that the dot on the wall made a pretty big circle, maybe a yard in diameter. Nudging the butt laser slightly I was able to make that circle a LOT smaller. If I hadn't done it I guess the butt laser would have been off by maybe an inch at the top. Now its not.

I wish the instruction video would have been longer, but my first experiences are very promising.
