Yeah, wing bars are sexy, but I don't think they'll necessarily solve your problem. Do your hands go numb when you ride on the tops of your current bars? The wing bars are a bit more ergonomic for riding on the tops, and some people like to use the flat parts to go into faux-time trial mode (more support on the forearms for better control without aerobars). However, you should be able to rest the heels of your hands on your bar tops and not be numb. Maybe you need different gloves? Maybe you need to change your fit or size of bars or hoods..? I will sometimes get numb pointer fingers when I have to do a lot of hard downhill braking from the hoods, because I eventually pinch a nerve. I also tended to make those fingers numb before I put gel pads on my bars, but I think that just served to change my hand position at the corners. One thing the gel pads did is to flatten out the tops of the bars, but they were flatter all the way to the corner bend, where I apparently needed it. The flatter tops makes it more comfortable to ride on the tops, but numbness and pinching nerves in my hands weren't an issue there.
