Question...just picked up a used set of irons that came with True Temper DGS300U. I have never used this shaft, 'Unitized'. Can someone offer the changes it creates to a set? I typically use DGS300 (no 'U' for Unitized). Thanks.

For all practical purposes, the DG with the "U" designation is a parallel tip S300. The parallel tips differ from tapers in that they will weigh different amounts as they are trimmed, whereas tapereds will all weigh the same, regardless of whether it is a wedge of #3 iron shaft. Playability differences are slight...at least in my opinion.
