Hello robertwb and All,
Thanks for the Janet Evans video.
I am impressed at how she attacks the water (she is strong!) - how she far she lifts her head out to breath (sort of like in a fly stroke and perfect for sighting open water - but maybe not as fast as rolling more to the side to breathe?) - and at first look anyway; how underwater her stroke looks like early vertical forarm and so similar to video of current swimmers.
Cheers,
Neal
