Nigel,
The only way to find out is to give it a go. It either works, or it doesn’t and besides you’ll probably learn something new along the way.
Asking for advice on these forums invites negative and unkind comments which may well be the truth, but do they really matter?
FWIW, despite knowing full well that it’s a complete and utter waste of time, I’m an avid watcher of golf instruction videos on YouTube. Judging by the number of subscribers and views these guys command, I’d say I am not Robinson Crusoe.
