Priddis vs Swallow vs Dal Santo???

[Jabbott]

Stuck between these three for my 4th midfield premium. Others opinions would be great!
Current midfield is:
Ablett, Murphy, ???, Selwood, Shiel, Magner (McDonald, Ledger)

Priddis - Really consistent, worked well for me last year. Doesn't seem to be in too many teams.
Swallow - Up and coming, good fixture for the year (plays GC and GWS twice), and should improve this year
Dal Santo - Always averages really highly each year, good early run for season, generally has a poor game which brings down price; worth getting later?, more expensive
