i used the stick-on and did not like the result. the throttle could fry eggs and the left got warm. problem was that it was heating the bar where as the throttle had that nice plastic tube to melt.
i would consider those oxford, but i use heated gloves that cost about the same and go with you....not attached to the bike.
