One of the more appealing points of going to a loop is using a much-lighter tied-in nock set to keep the weight off the string... It's also a much cleaner look aesthetically, in my opinion...

What are people's thoughts on tying a bit longer nock set underneath the nock? I've seen several target shooters do this, as they believe it allows the release to exert slight downward pressure on the nock... I just got through watching GRIV's DVD, and he only ties one nock set beneath the arrow apparently.
