I like the idea of asking for RNH. It's hard to know what will fly in your league (your rules are WAY different than my league), but if you assume this is a good time to "sell high" on Kunitz, I think that RNH's value is lower than it will be next year. I'd be sure to get value if you trade Kunitz now, but I don't think its realistic to be anywhere near this pace next year, so keep that in mind. Hope it works out for you.
