(Also, if you're not reading Lauby Industries, start checking it out! I owe him a link or three for all the help he's given me with my Not-So-Secret-BoLSCon-Oops-WarGamesCon-Army.)

The second picture illustrates my biggest regret with the army. You'll notice the Wargor on the right is significantly lighter, and cleaner, than the other models. That's because I dipped my Beastmen army.
I'm not dissatisfied with the army as a whole, but I wish I'd passed on dipping the character models and the Shaggoth. Frankly, they looked better before I did it.
I think dipping is a viable technique if it is used in moderation. Also, I didn't control the flow enough and allowed the dip to pool in places it shouldn't have. Still, in the future I doubt I'll dip an army. The washes are too easy to use and don't lend themselves to the same mistakes.
