On this topic, what do you guys have to say about the impact vs timed versions? I've been leaning towards getting the impact grenade, with the (possibly misguided) idea that it could be thrown or used as a trap as in this video:

That said, I guess you could roll a timed grenade, which might be easier for hitting someone around a corner. Thoughts?
