Disagree.
Correct me if I'm wrong, but there are only three things that are crucial for racing:
Pace in large digits (110 falls down on this as you can't reconfigure the display)
Distance/time (what running watch doesnt have this anyway!?)
Bluetooth for immediate upload for strava-bragging purposes (once back to the car and the phone).
Joking a bit about the last one but seriously (and I have a 110) the cable connector for the 10/110 is a crap way to upload, the connection is flaky, and I have to hunt round the house every time i want to sync (i.e. nearly every day!!)
Actually sod it, I can't stress enough how important bluetooth connectivity is!!
Further:
the 10 is bulkier that the 220.
the female version is smaller, yes, but only comes in "girly" colours
As others have mentioned, the 220 is really cheap now (John Lewis seem to occasionally do it as a special buy, might be worth checking)
I don't know how the 10 or 220 compares, but the 110 is really slow to pick up a signal - I've lost count of the number of times I've had to set off without a signal.
