I bought the D3 (regular flex) off the shelf without much thought months ago. I recently read that the D2 provides higher launch and lower spin than the D3. My buddy has the D2 (stiff) and I seem to hit it better and longer than my D3. My question is: is there really a difference that I as a 7 hdcp (age 58, swing speed 95) would notice or am I just thinking I hit it better and it is all a mirage. If there is a real differnce between the two and it is because of the D2 head, is it possible to purchase the D2 head, assuming the Surefit system is the same as the D3?
On another note, I am headed to Sea Island Thursday for both iron and drive fittings. I hope that the driver fitting will also help answer my question as well. Thanks for your help.
