I caught a recent match between Borg and McEnroe on the Tennis Channel. I was pleasantly surprised to see Borg now using Federer's stick (Wilson K Factor KSix-One Tour 90). What surprised me the most how much his backhand had changed. Borg used to have a really wristy two-handed backhand and he would let go of the left hand at the follow-through (as a kid, I jokingly pointed out that Borg had a one-and-a-half handed backhand). His current backhand, to me, looks like Bjorkman's. Both hands now stay on the racquet up to the follow-through, and there's much less wrist action involved. Anyone else catch that?
