Did you use 91% iso or 99%? It might be all tacky and pliable because there's still a bit of water in it. I personally hate the sticky gooey texture, because it's such a pain to handle on the run. That's why I usually whip mine over heat. It turns tacky and pliable to non-sticky and waxy, or a non-sticky opaque shatter texture if it's pure enough. IMO, a lot of it is highly strain dependant, as some strains naturally produce more waxes than others. Of course it also depends on how long you rinse for, as the longer you rinse the more non-cannabinoid substances you extract as well.
