I have had some issues with clogging up the poppets when I move hoppy beer to my brite/dh tank. So I took care of that by silver soldering a barb fitting to the bottom of a corny lid, added a valve and a flare fitting. I have a piece of 3/8 silicone attached to the barb so it gets to the bottom of the keg. Worked much better than just attaching it to the beer out post and it was also quicker to fill.
