Looking at how similar, or dissimilar, these 2 shafts are in regards to their playing characteristics. Both .370, and regular, of course.
TT0100 vs TT0068
They are very similar shafts. The Score is a combination flex and was a stock steel shaft build for a major OEM a few years ago. The XP is a discrete flex, coming in the R300, S300 options. The XP has a low bend point and a soft tip, where the Score is more of a mid/low bend point and med/soft tip. So, the only real difference would be the XP may be a little softer feeling, but since the Score is a combination flex you can adjust the tip trim to play softer if you trim less from the tip than the designated R or S trim instructions. The price difference is due to the fact that we were able to buy a large quantity of the Score from True Temper (over production for the OEM that they never took). It’s a really good shaft that we have had a lot of success with. The XP was discontinued by True Temper several years ago.
