The line feeding is a good point. I have started doing the same as well. I agree with you in that if they aren't taking the offering, but they are taking everyone else's, adjust the speed. I think too often, I get stuck in the trap of "oh it will be ok" "I just dont want to fool with adjustng the weight."

I saw on a recent post about Herzogg's video, and that speed was discussed. ( the faster the better ) I wish my wife would think to put that video in my stocking.
