I haven't got the Spindle so far (during the best run at it I had, my inet connection crapped out when we were at the door of the boss room - thanks to Deutsche Telekom), but I got the Omolon Eirene RR4 from the gunsmith last week with luck in the chamber and mulligan perks. It has bigger impact than the Spindle (edit: that's at least what the wiki says - edit 2: the wiki apparently is wrong :p), handles very well and has very good zoom optics. What do you think?
