Laurie from the UK here. Just logged back onto these boards after some time. I haven't got a TT but you might have just encouraged me to get one!
I have only been swimming once a month this past year due to family pressures - I have a little daughter and another baby on the way! But am going to try and go at least once a week from now on and will investigate the TT. I'll look to post how I get on here too
