Welcome Judge25. Take some time and check out the information over there including tutorials--------------------------------------------------------------------->
Just about everything will affect your drives, its a matter of practice and experimenting to see what works for you. You'll need to check the wind speed, wind direction, spin (not as important for driving I think), club selection (The auto caddy does not always pick the best club so check this every time), swing selection and most importantly...the accuracy of hitting that darn white line.
I have heard people claim they can aim by hitting early or late of the white line but I was never comfortable with that. Figured if I couldn't hit the white line, how can I accurately stop the meter just in front or just after it. But that is just me.
Oh, and don't be in too big of a hurry to move up in tiers. There is a discussion about this on my blog post. Check my profile page for more on that.
