So I finally quit whinin' about cold fingers on my morning commute and went and got myself some Oxford Heaterz. The install was pretty simple to do, I just wired it to my fuzeblock for switched power, and was off to the races (actually just a quick ride down I-95 to see how they did).
I also went ahead and installed the CRG bar-end adapters for the arrow mirrors I picked up from Snowytgr1 a while back. I had originally been using my OEM bar ends for that (I had them milled down a bit to fit the mirrors) but I found that they spun too much to be useful, plus they vibrated a ton while riding down the road. I'm using the stock bars, so I was a little worried about buzziness after taking the weights out, but I've found they actually buzz less now than before, so I'm glad I went ahead and did it.
