Basically, make your initial kicker be someone who is a 'stud' for his career if you can - don't draft too high though. If you can get Vanderjagt, Elam, Vinatieri, Akers, Wilkins, etc. While some of them might not be having the best year (akers specifically... heh), as long as they don't get injured (heh) they are basically unquestioned starters on their teams from the beginning of the year to the end - they are established.
After that though, during the season, ride the hot kicker. I drafted Vanderjagt in two leagues and Kasay in two league, now I have one league with kasay, two with rackers (one of which has vandy too), and one with bironas. Or something like that.
