As the other girls have said...

Ride Ride Ride

Ride as many bikes as possible before deciding. My first bike I didn't test ride a ton and settled with a WSD mountain frame and ended up being a bit too small. My road frame is not WSD and I love it. Don't just listen to your husband when it comes to fit, ride a bunch. WSD is great for some, not so great for others. Be sure to try both out so you know what you really like. Also, some lbs are more specialized in sizing than others, so try to find one that really spends the time making sure the bike fits. I know some in my area will charge you a little for a full fitting but it all goes toward the bike in the end.
