I have a Adams Redline 460 driver I got for $75 new off EBAY, that I love. I have tried
Cleveland launchers and
Callaway 454's and I would not trade my Adams for them.
But to answer your question, the first step if possible is to go to a golf store and see if you can get your swing speed checked, also try a few
clubs on a launch moniter.
If you know your swing speed it really helps narrow down what you are looking for in a shaft. If you are on a launch moniter it helps to see what your normal ball flight with each club as well as a launch angle which may give you an idea of the loft you need.
If not then at least if you know I far you hit your other
clubs might be a good idea as to your swing speed.
My guess is that you will need something of at least 10 degrees, 7 is way to low even low for most pro's these days.
As far as offsets, Draws etc. the big question is what is your ball flight now, what ball flight are you looking for and 2) how much do you want to work on your game to achieve that ball flight? also how ingrained is your current swing and do you want to change that swing?
I would avoind spending a lot of money if swing changes are going to occure, no matter what the cost of the club is if it has the wrong shaft, club head etc. for your swing it will hurt more then help.
