I rode from MI to FL recently and my hands were in A LOT of pain with the temp in the 30's and no heated grips.
My previous KLR had heated grips and I liked them but needed some controls other than high or low. Low was to cold and high felt like my hands were burning.
If had to do it over again, I would get heated grips, set them to low and have Hippos to keep the wind off my hands.
I dont like heated gloves, they are warm but not as tactile as I like.
