I would second the rift. Although I don't personally own one my close friend does and I have messed around with it plenty. The 154cm blade will be great for your tasks and the open back design will be easy to clean after field dressing. I have the rukus you mentioned and I love it. If you could find a good deal on one it could be a great choice.
So what's up with the Rukus? It was right at the top of the list until I started trying to find one! Why discontinue it? Too big for edc or something?
