Hand-warmth is extremely variable between people and my hand circulation is crap. Today, I used Endura Lobsters but it was probably about 1-3C in London at 7.30. Then I switched to Black Diamond ice climbing mitts for standing around outside all morning. I've never been able to use them on the bike for long without getting too hot except when I was in Alaska or Finland.
Pogies are awesome, though. You can still feel your controls, but they're super-toasty. I saw some great home-made ones in Harrow the other day. Looked like some fleece material with gaffer tape outer. Well worth trying if you live up north and get cold hands.
