The bigger changes from stage 1 to stage 2 came in the fairways, hybrids and irons moreso than the drivers.
It's a good club, great for golfers of any talent level, very forgiving if you don't get the tour/pro model. Adjustability is a nice bonus too.
I don't hit them personally but I've tried them out at work and between 1 and 2, I don't get any extra distance or better results.
