OUCH!
As has been said 34/70 is so safe and reliable it's a hard yeast to beat.
That new Ale/Lager hybrid Strain Nova Lager is also very safe and easy to use I've found (been brewing with it most this year).
S23 would be worth a burl as well it finishes dry.
So what Coors grist look like is it pilsner base with a splash of rice malt?
What hops are in Coors?
