Fundamentally the same composition, though it bears mentioning that Head was historically mum on providing the public the composition percentages of their racquets through the 1980's. My best guess is that they are 90% graphite / 10% Fiberglass composites. The Graphite Edge and Director were more like 80%G/20%F.
I have owned and played with both TXD and TXE. For some reason, I could never get used to the TXD - the sweetspot is rather lower, and the elongated head just felt 'wrong' to me, though the heft and balance were (on paper) to my liking.
