Z-Strain is a variety originally sold by a vendor known as Kreeper. There is some controversy over the origins of this variety as Keeper was known to order spores from other vendors (like Hawkeye) and rebrand them. Regardless, Z-Strain has stood the test of time and has beautiful spores. A staple and much loved variety by beginners and advanced microscopists alike.
