I am new to skydiving; only been in the sport for about 8 months. I am looking to purchase my first complete rig and I hear a lot of Performance Design main, and in a few cases Performance Design reserves being labeled only as a "PD 190" Since PD only makes only type of reserve it is obvious that when someone says they have a PD reserve in a 193 size, they really mean a PR 193. But since PD makes multiple types of mains in a 190 size, in F-111 and Z-P material, how do I know exactly what type of PD main it is? The last person I asked said, "I don't know if it's Z-P or F-111, look on PD's website." But that helps not at all. If there is a certain standard that I'm obviously not aware of please let me know.
