I was originally fit with a stiff flex Diamana S+ (61g?) and fought a two-way miss, with a hook being my big miss. The fitter changed my shaft to a D+ which might weigh about 10 grams more. Do I need to change the weight in the clubhead? I hadn't thought of that when we were going through the fitting process.

I ask because I have finished a few rounds with poor driving. Of course, it could just be a poor swing, but my last two rounds have been 38-42, and 36-43, going +3 and +5 on the last three holes.
