None of the above. I'd do a 178 ELDX, 180 TMK, maybe 165 TGK, or Berger 180 Elite Hunter.
Something soft-ish, good BC for velocity retention and wind performance, starting at moderate velocity, and on the heavier for caliber side of things, has been my preference for a while now.
Monos need speed to work, and tend to bleed that speed off pretty fast due to low BC's. Start a heavy mono slower, and it's not going to work well at all.
Light and soft, going fast at the muzzle is not what I want either. Lots of the issues people have with soft bullets seem to me like they are due to very high muzzle velocity.
