Goodyear Eagle F1 Asymmetric 2 235/45/17 .. Would recommend, Pricey but they seem like they are worth it so far 
I'm having variable results with these, which are likely to through the whole tyre threads into disarray 
At the budget end, the Runway Enduros that Taxi Al mentioned or the Accelera Alphas are better than most on Omegas at the budget end. Although wet weather grip is not great, they are not as dire as most budget offerings. Kumhos are OK, but more midrange, and lack feedback when they are about to kill you.
Not disputing you have doubts about these .. but then again, you do have a "particular" driving style that demands "particular" tyre characteristics ..... 
Others may be able to survive quite adequately on a lesser tyre .... 
You misunderstand. I have a set on the rear of one Omega, and its fine. Not superb, but pretty reasonable.
I have a set on the rear of the other, and they are disappointing.
Hence, the same tyre, effectively on the same car, but different results. Hence, potential for disarray in our joint attempt to catalogue tyres
