Could be a good choice for longer ranges. Although the JSB types do really seem to perform very efficiently in sub 12ft/lb guns. But it depends what your barrel likes. My s200 will shoot JSB's but they become unpredictable in wind. The lighter mozzies it shoots spot on with a very clean barrel, giving less wind and predictably so. It is the opposite in my Pro target. It loves AA field and JSB 4.53, but the barrel must be leaded or it gets really fussy. Now I've got a bit of lead in the barrel they give less wind and actually fly a bit flatter than the mozzies Seems to be about finding the right combination and if they shoot best in a clean or leaded barrel.
