Greetings: Then we're defining ratio differently (not to speak for Fenton). Changing the front weight has nothing to do with the action ratio. I believe what Fenton referred to was replacing lead with help from the assist spring. Then you do have the same hammers, ratio, BW, different leading, because the assist spring takes the place of some of the lead. The action would therefore have lower inertia. David Love I see you haven't quite understood the balance equation correctly David. Changing the Front Weight most certainly and undeniably does change the (SW) ratio. A most casual of glances at Stanwoods formula reveals this. Again...this is part of why you will find any direct translation to another protocoll... the distance one for example... quite difficult at best. Review Stanwoods formula. R = (BW + FW - WW) / SW Clearly a change in FW changes the value of the entire left side of the formula, and hence the equivalent R on the right side. Cheers RicB
