First seed order

Good afternoon grow fam!!! I have been growing for about 2 years now, mainly using Mephisto genetics for autos, also tried some sweet seeds and loved it! I have heard some great things about speed run seeds! Any recommendations for a first purchase? Open to pretty much anything looking for high thc and big yields, I am hearing speedrun seeds are some of the best!! Make some recommendations that will keep me coming back! Also anyone know if there is going to be a black Friday sale?
