hand guards and heated grips

[Roper_imp]

I'm planning on getting a set of hand guards and heated grips installed some time before the end of October, and I wanted to a little insight from those of you that have been using them for a while:

Regarding the heated grips themselves, Honda OEM or aftermarket? which is more popular? My gut tells me Honda OEM.

Regarding the Hand guards: I currently have a Dart Marlin Screen (Smoke) and I want to keep up with that same "blacked out" look, so if i get hand guards that are clear, i'd prefer if they were also heavily tinted. The only one I've seen like that in my limited research is the Chicdesign model (https://www.samurider.com/?p=17262). Are there any alternatives? It's worth pointing out that i'm also not completely sold on them being transparent either. If there are any solid black ones i'd take a look at those too.

What are some common things i could accidently permanently ruin due to inexperience while installing heated grips?

I have the Chic Design hand guards in the smoke color. They match my wind screen. They're beautifully designed and engineered. Mounting them is fairly straightforward. I haven't had a chance to test them in really cold weather, yet. In cooler weather and in rain, they do an admirable job.
