Joseph,
One more thing, what I have seen in 6 lugs are slim on what's out their and you have a little more to pick from with the 5 lugs. I have been looking for 6 lug wheels for my Yukon and I am having a hard time finding something I like. Just putting my 2 cents in.
I know what ever you go with on the Blazer it will be bad a$$, your just thinking to hard about this. At the end you will pick something cool..
