I've decided to try jumping on the hand canon wagon for a bit. I just got Her Mercy about an hour ago and landed a pretty badass roll, IMO (Sureshot IS, Zen Moment, Speed Reload, & Hidden Hand). That's pretty great for me, I think. It already had nice impact and now it'll reload quickly, be stable, and have improved target acquisition twice over. I'd love to get some opinions from others, though. And just in general, what do you guys shoot for with the rolls?
