RE: fall-away or whisker biscuit?
When I went from a two prong shoot through to a WB around 2002-03.... I thought it was the greatest thing since the box that you can open up and put ice directly onto your beer in. Three years ago I tried a drop away, and now they are about all I recommend and all I use.
Nothing wrong with the WB though... great rest still.... but I do favor drop aways.... less contact is mo' better in my experience.
