Finally got the setup that I like and everything is dialed in.... Can't explain how much frustration the edge holders caused me... But was able to take these for a spin and just love the ls2 holders. And the peace or mind that the steel is locked in by a bolt again.
I ordered the holders purposely avoiding the versions with the red accent. The eBay listing I got it from even had ones with black accents showing, but it was a bulk ad for various sizes so I got whatever they had in my size. Oh well. When I have time I'll use a bit of acetone to remove it or really fine grit sandpaper and wet sand it off and some plastic polish to match the gloss back.
My setup is currently as follows;
Standard tongue with embroidery
Superfeet carbons with the red footbed out
Tuuk ls2 holders
Ls3 steel profiled to quad zero and 9/16" roh
Elite yellow waxed laces
Finally a happy camper now.
My advice for those who are going to order these, just get the boot and have the holder of your choice that you are used to, and currently use, mounted. Save yourself the time and money of getting holders swapped multiple times like me. I actually didn't mind the step holders but aesthetics got the best of me.
