I am skeptical of lme, so I always use DME now. I have not had a twang from my extract batches, but I do notice a cleaner, crisper finish in my PM batches, even when I use liquid yeast starters in both. That being said, I still like extract batches every now and then for ease of brewing, and have a few recipes that I really like. I am brewing a high gravity IPA from extract right now, but started doing late extract additions and have gone to 4 gallon boils to help the end result as well.
