I use the players with those SAs in the specialist kicking lists. If I haven't enough then I fill with the other SAs, I've had quite successful free-kick takers who have the Penalty kick SA, and Corner kickers who have Free-kick SA. Where there are left/right options (Free/Corner kicks) I use the position on field as a guide to the column to put them in, not which foot they prefer. If they are a centre-field position (eg. MC) then they go in both columns. If they start missing out then I put the player concerned to the bottom of the column and shuffle the rest up to give another player a go.
