Week 19 Dilemma

While I plug away on my spreadsheet, manipulating my budget and examining line-up permutations and combinations in anticipation of the double week, it's becoming increasingly apparent that my planned midfield of 3 "big wheels" will not happen this week b/c the strikers I want cost too much, and the GK spot may cost a lot more than the last few weeks, where I held a dirt cheap Kirkland. So, of the following, I would LOVE to take 3, but will end up with just two of them:
Gerrard - 15.xx, WAT, @ BLA
Ronaldo -- 16.xx, @ AST, WIG
Barton -- 14.96, BOL, @ SHE
Downing -- 12.68, CHA, @EVE
Arteta -- 15.66, @ RED, MID
[if Jensen were not a doubt with a hammy, I would consider him as well]

Sonme considerations: I also like Downing's match-ups in week 20: @BLA, SHE; I expect at least Ronaldo to be in nearly everyone's line-up in our group; cheap defenders are not an issue for me..

EDIT: In terms of the GK position, I've decided that I'm almost certainly rolling the dice with Niemi. I am sticking with the notion that for the cost of 7.71, there is somewhat less risk than investing 13.xx for the likes of Lehmann or Reina. But more importantly, the extra units lead to a stronger MF & front line for me. I'm basically considering any positive return from Niemi as a bonus. I can't really seem Fulham giving up too many goals and they have 2 very winnable games against bottom feeders - what more do you want for the price. Hell, it's just as likely that Lehmann or Reina give up at least a goal in one of their games - so if that's the case and going to happen anyway, why spend the extra cash for a potential return that is not that much greater? I guess the risk is in the Cottagers not winning those games (i.e.: the extra -2 for a loss sucks), but Niemi is a great shot-stopper and I expect him to make loads of saves over 2 games, that will translate into some decent points.
