I've got lots of old weed myself. I did make oil with the oldest stuff, but have two strains from the 16/17 spring crop in rotation now. I just found bags of the first Ass Cheese and Gorille de Raisin I grew. Both were crossed with Sleepy {powernap x sinmint cookies} making Sleepy Ass and Gorille Endormi. I'm excited about shelling out the seeds more so than the actual smoke.
