What do you guy recommend when changing handlebar warmers? Going with OEM heated grips or going with like an aftermarket like Hot Grips?

I've used hot grips in the past with no complaints except that the wires a little bulky looking where it exits the grips but great heat.
My choice would be the OEM for a Cat unless theirs an issue with them for your specific year/model.

I,m pretty sure Hot Grips now makes one with in the bar wiring, I think I saw it in the Royal catalouge.
