On the lower topic, nothing I can add to what's already been said other than after several different brands of lowers in my vault, I like the feel, looks and quality of the DGW lowers we just purchased in our group buy.
On the trigger question, again, having built several lowers with several name brand kits and not so name brand kits, I decided I don't care for anybodies milspec trigger. I researched on and off for many months and after reading and sifting through tons of internet material and BS, I decided I didn't want to buy "massaged" trigger kits, not do I really want to "massage" one myself with the negative side affects that can occur. I decided I would buy someones single or dual stage triggers, well I finally did purchase a couple of single stage triggers on impulse right before Thanksgiving. I saw a Wilson Combat Tactical 3-gun trigger with a $55.00 discount and bought 2 of them. They were pricey, but I could not be happier. I plan to purchase a few other brands eventually, but for now, I'm loving the WC... It's like going out to eat on datenight... I have no regrets spending for the best steak on the menue, as long as it's great!
