Does the low balance point of DG 105 iron shafts truly help clubbuilders achieve higher swingweights without adding much weight to clubheads?  Compared to the standard Dynamic Gold, for example.  True temper once offered the DGSL shaft, and promoted it as achieving similar swingweights to the standard without adding weight as a result of the lower balance point of the shaft.  Is this also true of the new DG 105’s?  I am contemplating the TS1’s with the DG 105 shafts.  At men’s standard lengths, I’d like them to SW in the D2 range…will I have to add 6-8 grams of tip weights?
