The ISS was more of a piney/citrus minor lung expanding smooth toke. Somehow reminded me of some Sensi Star I had years back. I suck at flavor descriptions and it's been a long time. I do remember it being a very up and clear headed high, but didn't cause me any noticeable anxiety, no heart racing. The Sheisel was straight up sour grapefruit fuel funk. The odor/flavor would be stuck on your fingers and your tastebuds for lengthy periods. Wouldn't call it couch lock, but did have a nice body thumping or wave effect. I ended up flowering other phenos of these, but didn't come across the traits again. Those were the first two real genetics I ran after my first cycle of 3 bagseeds, I just ended up getting lucky and not knowing what I had at the time. Hopefully I can have some blind luck here in the future as well!
