Tuppy-G,
Check the shaft flex on the new club vice the old club and the swing weight. I think you might find the difference there. Even though a club shaft says regular, or stiff there are no standards for companies. I play a Penley Tour Light Stiff in my driver and a regular in my 3 wood. They have lively action but are probably really a x stiff and firm. A Grafalloy Blue regular is more like a senior shaft. Take the 2
clubs to a Club Maker and have them checked. That expensive club may have a cheap shaft, if it is an OEM shaft.
