I prefer string follow over set back limbs on an ASL. Gentler in the hand at release, close enough in speed that I can't tell the difference. However, the draw force curve is different, as Steelhead points out. The fact that it starts with less tension on the string means that it has to build it faster during the draw, stiffening up faster toward the end of the draw. A lot of folks don't like this "stacking" effect and don't find it as smooth as a backset ASL. However, the lower early tension seems to enable the shooter to get his muscles/skeleton in better alignment to handle the heavier weight toward the end, which for me makes it more pleasant to shoot.
