Happy to help, Saint.
Given you have Goldy, Sandy and 2 North Rookie Rucks, you can't do any Ruck loopholing with S Martin switching between the lines. He does of course provide Ruck cover if you happen to need it in the last 3 weeks. He can also be loopholed in the Fwd line of course. I can see Martin's scoring dropping with Leuey's return, but it still might be better than Wingards, whilst still giving Ruck cover.
Spina's not a bad loopholing option, though Ade does play game 2 in Rnd 22. Obviously good for cash generation though.
If you are comfortable in your most important match-up this week, I think I'd go option 2! It genrates good cash, which might prove important next week, or even more hopefully, you win this week and you can wait and assess for a week.
If you are not 100% comfortable in your main match-up, I'd go with option 1, for a bit of a boost this week, and some safety in the weeks to come. Though you still might possibly consider Spina over Redpath. If you are really worried about this weeks match-up, option 3 gives you the biggest boost this week.
I guess you can assess your match-up after the first 2 games, and see if one POD or other has caused reason for concern, or hopefully reason for relaxing a bit, and then decide which option suits your week best. Options 1 & 2 can even be left until after game 4 before you start moving on them, which is pretty handy.
Good luck
