I just had some sweet luck! Did the Shield Brothers strike and got my first Treads Upon Stars, then immediately after, the next strike was Omnigul, and I got a Grasp! (Third ever) I would say Treads has the better roll with reactive reload, zen moment and high caliber rounds. Grasp has rangefinder, fitted stock and last resort. Both dropped at 334........now if only I had this kind of luck decripting armor engrams lol! RNJesus I need my Infinite Lines chest with dis/str! Its going on a freakin year now!!! :P
