Von-I believe I have two sets. The first being a complete set of the Starlight Express from the Las Vegas Hilton, missing two. With all of the right, left and center break varieties, believe the set to be around 34 different strikes, two of the strikes only having left breaks. My second being the Heart and Stars strikes from the Silver City Casino, the Pony Express has two different fonts sizes and took me over three years to find. I have heard of other people looking longer and still not finding both. People will disagree with my choices, but these two sets have been a thorn in my side. There are singles or pairs of strikes out their that I will never be able to acquire, but I can live without them.
