Hi,
First post here.
I've tried a few. The one that had the best effect for me was 'Simple Golf' by Nevogt.
Plus - very 'simple' to learn - basic swing - keeps you out of the woods
Minus - You won't hit it long. Looks non-classic so you have to be able to take the jibes of your partners.
About every three months I wander away from it trying to find more distance - always regret it. When my round goes to H**** I find myself reverting to the Simple Swing and at
least I can finish with some respectable bogies and a par or two.
As a note I've tried some of 'break par in 2 week' online courses and ebooks and none have done a thing but mess up my swing. I won't name them cause I don't want to get sued
but 3 different courses had 'no questions asked' money back guarantees and when I asked for my money back the same guy responded to each and said to quit buying his 'systems'
To me that means scam but what do I know.
In any event be careful
Bob
