I'm a scratch as well ... but have limited playing time (14 rounds this year).   I really think it boils down to how much time you can put in.   For example, I played different Titleist blades for several years when I played more.   Now, with kids / schedules…

Bruce, 

Essentially, a lighter shaft weight can equate to faster club head speeds.  This change in weight could have also effected your launch, causing it to launch higher and carry farther.  I would be interested to know your ball speed, launch angle,…

Ben,

How long have you have you had your irons?  I would ask your Teaching Professional for a club fitting.  That way he can check the flex and loft/lies which may need to be adjusted.
