@O.I.C: I have plenty of purity seals at my disposal, so I won't need to mould or green stuff them. I have looked at the upgrade sprues, but I don't think I'd make my money out of it. Unfortunately, no one plays Black Templars that I know, and I'm not sure how useful these bits would be to anyone else.
I have seen green stuff moulding attempted, but failed. I'm not sure I'd be up to it since I have never actually used green stuff before. I have very limited funds to work with, too, and I'd rather not be buying the shoulder pads, I'm sure purity seals and other things I can scrounge up will be suitable. Yes, I will try to have some picks up, but I will not be starting this project for at least another month.
@Raven: I did look at the Space Wovles too, but I'm not sure they're what I want either. The Dark Angels veterans are really appealing to me, I love the robes and hoods
Thanks for the suggestions though guys.
