It looks good Pete. I'm considering treating myself at Xmas.
the 735 XT has a look of the Forerunner 220 which I've had for around 4-5 years now and the only issues I have with it are battery life which used to be OK for 5-6 hours and now is down to around 3-4, and then the occasional software glitch as I think the device isn't supported as it was in the early years.
I haven't actually looked at what is in the market at the moment so pleased to see your comments.
