It sounds like a completion trade BB - so breakeven isn't as crucial.
However, Laird does have a breakeven of 111, which he has only got once this year in his 7 games. Depending on your other trade movements, I don't think you would have to move on him this week.
Rance has a relatively high breakeven as well, 116, so similar argument there. However, Rance does have the ability to obliterate his and hurt you more financially in a one week period.
Interestingly, neither have scored a century in a long time. Picking the right one will be a masterstroke, if indeed one of them returns to the levels the majority seem to think they are capable of!
