Kinetic Slot Shotgun Recommendations?

Coming back to the game after about 6 years and trying to get back into the Crucible/IB scene. Historically I've run a pulse or scout kinetic (blast furnace mostly), and a shotgun energy. I've been playing around with a few things, but found a couple of the new energy pulses that I really like, which leaves me looking for a kinetic slot shotty. Currently playing around with an old Dust Rock Blues that I had in the vault (slideshot, rampage). I've tried a couple slug SGs and didn't really like them. The rampage feels like a wasted slot, and I was hoping to get a different one that's maybe slideshot/opening shot or something else that would give me more range.

But, I'm not super familiar with the new mods. I've seen a lot of talk here about slideways - is handling more important than range now? Or does it depend on the frame?

Also, I've seen some recommendations for closing time, which seems good since you're usually low on special ammo in crucible, but it doesn't seem to give as much as opening shot. For something like a shotgun where you're pretty much only taking one, is opening shot still better or am I missing something?

Any other perks to consider that I maybe haven't heard of? Thanks!
