Shortys
I have always liked the fact that Shortys 7/8" come with the low head nuts, which means they fit well on all the normal cast baseplates.
The standard (taller) nuts that come with most 7/8" bolts of most brands fit best if you are on forged baseplates that are thinner, but often don't tighten enough on the regular plates, so many people have had bolts loosen off or even fall off when using them.
Never lost a single Shortys bolt or nut, that I can recall.
Also the size of the head of the bolts, being smaller than most, is easier to do up and to me, they don't have any issues pulling through, as some people have said, which is why they use bigger head bolts.
