Ask yourself, is your current saddle and aggressive riding shape? The LBS can recommend similiar shapes if you bring yours in, and should let you try them for a few days as long as you don't damage or scratch it. With my incredibly limited experience this last week I wouldn't buy an unknown saddle any other way. I had soreness in the privates (specifically not the jewels) when in the drops prompting me to a cutout saddle. The Specialized Avatar felt flat and I wasn't "in the saddle" so to speak. Tried the Specialiezed Romin Evo Comp which is more aggressive and wide cutout and right away huge improvement. I'll ride it 20 or miles today and see how it feels.
