Are we opening this hand?

2/2 live 5 to call 8 handed

Rock straddle to 5 is out every hand, preflop positions are weird every hand.

Effective around 1100 or less.
CO rock straddles to 5.
Some limpers including BTN.
We pick up KhKJ2h in LJ
Only Co and HJ have yet to act, they are tags, if we open, they'd fold alot besides good hands. Co would check 90% of the time unless he's got a good hand.

Are we opening or just limping?
