So I tried both pretty extensively. Without a doubt Spinning Up worked better for me, especially when I prefired before the target came around the corner. My overall opinion on autos is that they still don't quit fit in though. Pulses are still a better option from medium to just inside scout range and handcannons especially the palindrome archetype with LitC dominate inside that. The biggest upside to the auto rifle is that you aren't punished nearly as bad for having shitty aim, like your's truly. I wish I didn't break down all my high impact autos a while back because I'd love to try a legendary and open up a slot for the trespasser, which is extremely fun to use BTW! Anyway let me know what you guys think about the Suros and if you have used it which perk do you prefer.
