So I went to New Paltz for two days for instruction in the TI method. It was fun and informative but all done in an Endless Pool. haven't been able to get to a full pool since, so I don't know how well this will work. it's also clear that I have a lot of practicing to do before I can consistently do this correctly.
Anyway, on Monday I will test drive the method to the extent that I can and see if my times improve.
