Lug nuts for Pro Comp wheels?

I just purchased a set of 17x8 Pro Comp 7005's and need to figure out the proper lug nuts before mounting them.

From the research I've done, Pro Comp wheels seem to need ET lug nuts.

I purchased these lugs but I believe they won't get enough bite on the threads:

Spline lugs (19mm diameter)


I got these from a friend but I want black lugs:

Spline ET lugs (21mm diameter)


Tonight I purchased these via the eBay sale but I'm worried they are too large in diameter to fit in the lug holes:

3/4" Hex ET lugs (23mm diameter)


Does anyone by any chance know the diameter of the lug nut holes themselves or can give some guidance? Are spline lugs necessary?

 

I have pro comp rockwell 34. I went with these. They also come in black.

 

Did you have any issues with not getting enough grab on the threads? I've heard some people running pro comp wheels don't get enough turns out of standard conical lugs, therefore move over to an extended thread lug.

 

I just put them on towards the end of January and haven't done a rotation yet. The shop I had put them on didn't say anything about it.
