I attended a TI seminar a few years ago and was lucky enough to have Terry Laughlin himself as my coach. I loved the clinic, Terry, and everything he taught me. I have so many bad habits I would need Terry 1-on-1 for a few months to have a TI type perfect stroke unfortunately. I am more of a miler, open-water type swimmer so I cannot comment on the "sprint" aspect of your question although Leslie's is a drop-dead sprinter and world record holder so I'd agree with whatever opinion she has.
