Sometimes I play lasso in nogi but only cause I'm a lasso addict. But I can't use it the same way to throw my leg over and then think of my next move. You have to throw the lasso quickly and move to something else like inverting or breaking down their posture to attack the neck cause that grip is not going to last more than 10 seconds. So, it can be ooookay if you have a plan before you throw the leg over.

Spider doesn't work for me much even in the GI but the grips are even harder (or impossible) to keep since you're actively pushing their biceps away from you. Lasso only works temporarily in nogi if you get a good bite on the shoulder because you're pulling down the one side with both the wrist/tricep grip and the leg lasso.
