I'd think that anything the Huey can do currently, would be carried over to DCSW2 and the new map(s). So basically and SAR type missions you can do now.
That said, I'd also consider Arma 3, and some of the community made missions (there's a neat auto-gen series of heli missions on steam workshop), to get your SaR fix. DCS does helis better from a physics/systems stand point, but A3 has a broader hanger and range of content mods available. Plus the advanced heli models they introduced last year are still pretty challenging/rewarding to fly (IMO), so it's a good balance of features. A3 has a more visually engaging landscape to fly over (although is more of a performance hog as a result) as well.
That said, assuming you're on the rig in your signature, I suspect neither DCSW2 or A3 will run well, or maybe even at all :/
