Well, I did get the clubs (2nd hand) that I felt was right for me: 1/2 inch longer than standard. I went out and hit with them at the driving range and it certainly did feel much better. My shots were much more consistent. If I went with the online site fitting, then I would have had to get 1/2 inch shorter (and some even recommended one degree flat as well). Although I am on the tall side (181cm or 5'11''), my arms are rather long compared to my height and I think that was the reason why these website recommended it(I think standard clubs are generally made for people who are 5'9'').
I still didnt get it dynamically fitted but I went with what I felt was right a I have tried other people's club that were longer and that standard clubs have alwas felt slightly short. The only thing that is actually shorter is the driver which is at 44.5 inch long and I certainly dont feel as if I have lost any distance with it (at the driving range I was carrying 270 consistently with my new driver).
So a message for those people who are thinking of getting club fitted through websites is, do try to get clubs fitted dynamically first. Just because your height and features are standard doesnt mean that your clubs will be standard.
