Calling all Energy Gel users

I've been using Gu & have found 2 flavors I really like: Chocolate Outrage & Peanut Butter. On my cold, long runs, the Gu seems even thicker. My training partner uses & swears by Power Bar energy gels. She gave me a sample of Green Apple. It wasn't as thick, which I did like, but wasn't totally crazy about the flavor...don't think I'm much of a fruity flavor fan. I noticed that Power Bar has a chocolate flavor. I've looked at Dick's Sporting Goods & my favorite running specialty store, but can't find a single packet of chocolate to try. I know Power Bar's website sells individual packets, but it'd be silly to pay for the shipping. Was wondering if anyone out there has tried the chocolate flavor?
