According to this article (which has set the Nadal haters and fans in heat over whether Toni quit or not), Toni says Rafa has made some modifications to his frame to get more power to hit more winners, after earlier attempts to change racquets etc failed or had little success.
I have to say he was serving pretty well with a heavier racquet. It’ll probably take him more training and matches for the groundies to start falling in more often.
