TheStack

I think the Stack system will be good for improving speed. However, I was very disappointed that stack system does not integrate with my Mevo Gen 2 for the wedge and putting training. Flightscope marketing says Membership includes Bundled access to Stack Putting (iOS), Stack Wedging (iOS), and the Learning Library (All Platforms). But doesn't say you need to purchase the Stack Radar. I feel this is misleading, another $289. I will continue to use for speed training.

Great for getting the feel of using your whole body to swing the golf club to increase clubhead speed.

The process is excellent. I am only in stage 5 but progressing nicely. The stack gets you moving in a positive direction!
