Airflow/Training Balls | Golf Monthly

I looked at the birdieball website and then watched a few of the videos. Perhaps this won't get read by most now but to those that have....that striking mat that has the 'correct' swing path lined up - surely that can't be the same for everyone, can it? Also, the way they say you hit off the strike mat they sell its equivalent to a slight uphill lie, isn't it?

Perhaps I'm looking too much into it given the references it's got and as the missus is happily saying she wants to be have a go with my bats...almost pressed the buy button. I think the only thing that stopped me was the lack of info re whacking it against a window (i'd play in the garden) as info on hitting objects with the 'ball' is noticeably missing.

Thoughts?
