who to bring in and who to bench (defenders)

[bob321]

Thinkin of bringing in either :
Scotland vs dogs (115 last year and last 2 scores have been monster)
Hanley vs richmond (35 last year but last 2 scores also good)
Leaning towards scotland as he used to be my number 1 picked def

And when i bring em in ill have to bench 1 of:
Malcezski vs coll ( 100 earlier in the year but last few games have been shower)
Mckenzie vs melb (82 earlier in the year but last few have also been shower)
Ibbotson vs gws ( no scores against them but has been shot with mcpharlin out and was inj last week)
Leaning towards ibbo just cos I have no idea what he might do

What would you do?
Cheering for any help
