Ap1 irons

Hi

I have a standard length set of a ap1 irons that are 2 degrees upright. If I have the shafts extended by either a quarter or half inch what effect will that have on the lie? For example would that make them 3 degrees upright or have no effect?

Any help would be appreciated.

Thanks

Hi Peter, For every 1/2" you lengthen your irons, the effective (not measured) lie angle will increase by 1°.
