Epiphanic! Glad to see that a light bulb went off in your head and things are now starting to click. You are headed in the right direction with your new swing. Expecting great results ahead. Congrats!
This device is a very clever, well thought out, and novel. This device is very innovative and is a credit to your active imagination and creativity. This device will reinforce and teach the golfer the skills and sensation necessary to develop the concept of extension and to maintain the radius in one's golf swing. However, the problem I see with it is that it is a useful tool for better golfers only. As you are well aware there are a limited supply of those around. Weekend hackers have many more basic flaws in their swing and need to address those areas first. You have to learn how to walk before you can run kind of thing. As such, this device will have limited appeal to a much smaller set of golfers. While I do not want to discourage you, the expense involved in getting this invention/product manufactured, marketed, and distributed out to the marketplace, particularly in the economy we are currently in would make this effort cost prohibitive at best. There is a lot of competition out there in the marketplace for a limited # of dollars available. Nike just got out of the golf business and the whole golf industry is flat now. Other manufacturers are struggling as well. If this device had a much broader appeal and the economy were better, I would encourage you to pursue its development.
