Yup. Twenty20 and hsc are my favorite breeders. They put in more R&D than almost anybody. Twenty has this one called "bad girl" that is just so crazy. The aroma is intoxicating like sweet gas with a touch of old school funk. HSC has plenty of gassy strains- vanilla frosting, vanilla creme pie, bigfoot glue, any of their OG's, headband, royal highness, the bling, some phenotypes of stoopid fruits, purple mountain majesty, notorious thc, don Carlos, collie man kush... They do breed a lot of fruit strains, but breed just as much gas/skunk. The market wants what the market wants and hsc puts out. Bigfoot glue is the best for straight gas/rubber that I've had from them and produces very well. If I wanted something that was just over the top fuel, I'd grow sour diesel. Haven't tried theirs, but I'm sure it's great!
