I made mistakes when I started with crossbow, actually when I switched to illuminated nocs. I had bought great "bolts" dead nuts accurate and matched to my crossbow but the internal diameter was odd so I was limited to lighted nocs I did not like. I ended up figuring it out on the second go around.
I don't know the website above but trust a good recommend from knightrider... Suggest you discuss the whole deal, noc to tip with them. Do you trust mechanical broadheads or want fixed, what kind of lighted nocs do you prefer. If you unsure about broadheads, discuss with the folks that "will flat hook you up". If you are an experimenter by nature let them know you are and want "standard" diameters etc so you can play.
Enjoy
