Help - which beads?

I feel like the little engine that could. I think I can. I think I can. I think I can. I've finished the first chart (A) of the Spring Things Shawl. I'm still behind schedule but I still hope to make it.

Now I just have to decide which beads to use. The young woman for whom I am knitting the first one of this shawl (I've already got plans for at least 1 more) for her wedding has square crystal beads on her wedding dress. I hunted a while back (somewhere around repeat 3 of Chart A) and couldn't really find the "perfect" crystal bead so bought three "not perfect" ones and tried them today in a sample of the first section of Chart B. I can't decide for sure which I like best.
If you have an opinion, please share it. The cubes in the middle are, I think, closest to what is on the wedding dress but I'm not sure what I think about them in this shawl. I think the clear with silver on the right is out but I'm not sure between the pearlized rounds on the left and the crystal cubes in the middle. The cubes have a nice opalescence or something which isn't showing in this photo (and this was the best photo) and they match the dress beading more closely I think. But I have to admit if it were for me I'd go with the pearlized rounds.

I'm going to cogitate for a few hours while I do something else and then if anyone has offered opinions I'll read them before deciding what to do. It's tempting to leave the sample laying around and see what the young lady herself says since I'll see her tomorrow but I kinda wanted this to be a surprise when all finished. Plus I'm not sure I can delay until tomorrow night since I am already behind and I think it's going to take me several hours per repeat of Chart B (and C and the edging at this point) to knit the rest. Which makes it unwise to dawdle much. Or be indecisive for that matter but somehow that isn't enough to make me just grow up and pick one.
