Just the responses I'd hoped for and needed, thanks. I'm eating up the gears practice suggestions for breast stroke too, plus all the practice examples you've recently posted, plenty to keep me full for a bit.
I can sense, without even trying yet, that the TT will be a valuable asset there.
P.S. In fact am trying to arrange a visit on the 13th. Admittedly, the cause is strong the location near (relatively) and the price is right. Hope to see you there.
