I have played 18/21 and 24/12 archer builds before, with bodkins and tatars. Using a longbow and tatars will let you shred other archers, horses, and light mail infantry. You can drop many players in a single body hit. However, if you are facing someone in higher mail or plate, tatars are a poor choice.
Bodkins are lighter to equip, and you don't need to scan the battlefield for an appropriate target. You can fire on any enemy you see and be guaranteed to do some damage. The upkeep is steep, but as an archer your armor equip cost should stay low enough to balance it out.
